Has anyone seen or heard when these will be available was looking at the pics on their facebook page earlier.
-
It took about 6 months to launch the 3D rainstorm, after showing of pics. Looks Baaaaaaaad!
-
Gotta ask Pyramyd if they are even going to import it, They don't import all Evanix Models.
I want one !!!! :) :)
-
they look hot !just seen it at pyramid air in 22,25, 9mm ...i dont understand 6lb pull on the trigger ! ??? ..is that adustable to a lower setting of perhaps 2lbs or do u need after market parts to reduce the pull ? ...jorge

Triggers are adjustable

Where ?
-
Just found it,...time to save for my Xmass present :) :)
-
saw it right i was just copying it to show it hottttttt !!!!!://cdn.pyramydair.com/images/AV-00461.jpg
-
Hummm, I assumed it was the Rainstorm trigger, but I just read the specs and it says non adjustable
-
Had the opportunity to handle one and it's definitely a BAD (insert favorite finishing phrase here) gun! Good lines, nice adjustability and all the normal features for the Evanix line. Aside from being a bit long in my opinion, it's definitely a very cool gun. Haven't shot it yet, guess I should probably inquire about that
-
evanix would be better off putting there energy at coming up with a beefed up or redesigned action for there .357 line of rifles. there is little to no mod that can be done with them using the same action from .117-.357, just my 2ct
that gun is certainly different not what I would call a standard hunting rifle

So you have checked that the action is all the same throughout the caliber range? What's the limiting thing in the action then that prevents any improvements?
-
According will Piatt, as you go up from .177 to .357 the transfer ports get thiner and thinner. In short no room or "enough meat" on metal to enlarge . He also stated the .357 was over bore from the factory and that they had to modify something inside just to get some part or another to even thread. So I have no idea why they would come out with a .45 without designing a new action something they should have did from the .357 on up. That is if they want non believers /people to really take them serious!
-
I think the sniper has a new designed action/reciver/block
-
Let's hope so, otherwise those who want a .45 to shoot in the big boys league of +200fpe will not invest in something that can't be tune to compete with the likes of Sam yang and Sumatra . I think they are more into selling the "repeater" angle than to compete. They could still make it a +230fpe gun even if it only gave you (7) shots. Big bore hunters would look at the fast follow-up potential . Just my thoughts :)

Well 1st reports on the .45 are in the 180 FPE range factory, and they mentioned it could be tuned up.
I had DAQs .50 and .45 Outlaws that where in the 180 FPE range, very effective weapons
-
Altho I need a BB like I need a hole in the head, the Evanix Tactical Sniper .45 repeater is just screaming my name. :-)
Hopefully the action/breech was redesigned? If not, that would definitely rule it out.
-

It still seems to have the same internals.
-
something must have changed, with the .357 it tops out at 130 FPE and if you go heavier ammo it start to get lower FPE, for the .45 to get 180 something must be different in there :)
-
That's what I thought too Manny, but one of our mechanical experts here (or on the yellow) explained to me that there is more surface area for the air to push against on a larger caliber - and this (including maybe heavier hammer, spring) might explain that incremental additional FPE.
But I also do recall Pyramid posting that the action on the .45 is different somehow - although I don't know if that FPE range in .45 signifies a really big difference.
It seems to me that Evanix (as a company) should consider their core value proposition (ie the reason people got really excited about them originally). Think of the legendary Ar6. The legendary Rainstorm in .177, .22 or even .25. They were POWERFUL and accurate repeaters - offering power to spare, and similar accuracy to many pricier guns in their caliber. I think that this started to slip with the 9mm Rainstorm. I think that the Evanix brains needs to put their heads together and take on board some customer feedback - because (in my very humble opinion) they seem to have drifted away from their core mission. I think the HUGE success of their legends (AR6, Rainstorm) might have made Evanix just a little lazy in terms of real airgun innovation. I mean the kind of research and innovation we see our own guys on this forum (rsterne, others) doing without a huge factory and piles of money behind them. The technology is obviously capable, but their business mission now seems to me a little "airsoft-ish" - meaning put out as many cosmetic varieties as possible, but with less real thought and innovation where it counts (and where the Evanix name stood for): power, power, accuracy and functionality.
I would buy an Evanix any day over almost anything else out there - but that loyalty is based on the past, and I really wish they would keep innovating where it counts with these .357 .45 and newer guns.
-

Transfer ports are larger and I believe there are some changes in the valve. One of the lads broke the valve pin so it looks like Evanix is starting to push it a bit with .45 design.
-
Jim Chapman should get one this week, lest see what he sais about it
-
Yes, this rifle has got my attention. Looks cool. Plenty of power for coyotes. And a repeater. And its an Evanix too.
According to the Pyramyd Air website, this rifle has a medium loudness. There are 2 buyers who put in their reviews of this rifle. One of the reviews was not very promising. They said the rifle is way too heavy and not backyard friendly. I called Pyramyd Air to ask about this rifle. They said that this rifle is backyard friendly.
-
Having shot a few of them now as they have come through, the loudness is going to depend on your backyard. I would call it borderline backyard friendly. If you have a bigger backyard and not a lot of houses around for the sound to reverberate off of, then it wont be too bad, but if you have neighbors close by, I don't think it would go over well.
I have shot the .22 and .25, both are hammers as you would expect. About the same power level as the Rainstorms. The triggers out of the box were very rough but after our techs adjusted them down to around 2 lbs, they were right on the money. the gun definitely has an interesting feel to it. Finding a good place to rest your offhand can be a bit tricky as the gun is very long and balances like a long gun. The adjustable butt stock is quite unique and aside from being a tad thin, works well. I'd make my own cheek piece if it were me, but the stock one does it's job. It should definitely be painted black though to complete the look of the gun.
Accuracy was not shabby. For bigger animals like yotes, accuracy out to 40 yards shouldn't be a concern. I was shooting 10 shot groups and was able to keep most of my shots in one large hole, a few here and there would wander but that was probably me. I was definitely more impressed with the .25, the .22 seemed either a bit too hot IMO.
Overall, I liked it. Not something I would use personally, but I don't hunt much and am not a huge fan of the tacti-cool stuff. I'm a traditional Rainstorm fan as far the Evanix guns go. But if tactical is your thing, the Sniper is the gun to have for sure!

Got a sniper on order, along with some 95gr, 105 gr bullets and some JSBs, should be here Friday 8)
looking forward to seeing what it can do, a friend has a 3D bull pup, should make for a good comparison of loudness and what not.
already making plans on how to quiet it down though ::)
have a nice 50 yard range in the backyard for testing and comparison.

looking forward to your reviews

Unfortunately PA didn't ship my gun until yesterday >:( so I won't have it until next Tuesday :-\
on the plus side I did mean woman about it as I had paid for 3 day shipping, they agreed to refund me the difference between the normal shipping and 3 day.
-
Got my gun today, came home a bit early to play with it. plain brown box, no manual.
initial impression, big and bad 8)
Cleaned the barrel -it was filthy, topped of the tank, had 175 bar in it already, tried to slapped a scope on it but my Nikon rings i had from a AR15 build wouldn't fit over the Picatinny on the gun, grabbed a different set and was able to mount the scope
did a quick bore sight. lubed a couple of 95 gr "pellets" and headed outside.
cocking action could best be described as "Gritty" :o , closing was smooth pellets chambered easily, much easier than my friends 3D
was raining so I only fired one shot to get an idea of the loudness and how close the scope was. Seemed a bit quieter than the 3D, still not real neighbor friendly but not god awful
Trigger was very heavy but crisp, need to find a manual so I can play with the adjustments a bit
hopefully after a bit more use it will smooth out... guess we'll have to see how it performs - weather doesn't look very promising though
-
glad it showed up though late. a lot of us are waiting on your results:0 I will do a anti-rain dance:)
-
Email Pyramyd about the manual, they sent me a link to one on their site.
Got a chance to put a couple of mags through and get it sighted in before it got too dark.
I also pulled the "shroud" well it is pretty worthless as anything other than decorations. There is a "bushing" pressed in that the end of the barrel screws into to keep it centered, problem is there is no way for any air to get past it, so you end up with a rather small pocket between the end of the barrel and the muzzle brake and that is it (about 1.5")
I'm making a LDC for and may just drill some holes in the shroud behind the barrel to try and use some of that wasted space.
-
Still haven't had a chance to do much more than make noise an put holes in things at close range, but the action is smoothing out and I was able to adjust the trigger.... Much better 8)
The scope I had laying around and hoped to use is turning out to be no good, so I broke down and ordered a new Konus, wife's going to kill me :-[
a friend is coming over tomorrow with his 9mm 3D, hopefully the snow isn't too deep and we get some trigger time...
I had hoped to have 4 different pellets to try, I have some 77gr JSB's as well as some air venturi 95gr and 105gr bullets. I had ordered some more 95 gr bullets from Hunter Supply but the package didn't get delivered today -worthless USPS 3 day my butt
-
Finally got to run a good number of pellets through it and some over the Chrono - setup was less than ideal but I got some numbers to start with, shooting 95 gr HP .356 it peaked at 777fps for 127 fpe. (may have been slightly higher as I had a downward slope on the string and I error'd on the first shot)
Shooting the 105s it peaked at 730 fps for 124 fpe. I was getting some good grps with the 105s and of course it loved the JSBs (forgot to run them over the Chrono)
Still shooting from relatively close range so the groups are nothing to write home about but are encouraging
Got some 90 gr EPP/UGs from Recluse35 and they are very promising as well, a bit of horizontal stringing and everything was hitting close to the Point of Aim
now to do some tuning and stretch its legs out a bit
oh, with my LDC in place the little db app I have says its only 70db compared to my friends 3D at 98db 8)

-
;D ;D I guess I'm getting to be an old traditionalist (old fart) the tac look although it lets you easily hang stuff off the rifle I will probably just order a Rainstorm in .357 after I get my compressor and a 4500 psi tank. I like the look and feel of wood just prettier ::) ;D
-
I guess I fall in the Old Fart group too. I ordered the Rainstorm. I love the wood on it. It's kind of a redish brown, lots of grain in the wood. I've been wiping it down with Old English and it really looks good.
I've been kind of thinking about the Tactical Sniper as a boat gun. I am so protective of the wood on my Rainstorm I hate to carry it around in my boat. I could throw the Tactical Sniper in the rod box and let it ride. I don't think riding around in a rod box is going to hurt it much.
-
I also went for the wood stock, 9mm Blizzard in my case. For me it was a price issue, I couldn't see me paying 200$ extra (actually 250 euros in here) for tactical look I didn't fancy much. Besides, I'm planning on bullpupping the gun at some point so it's the action I'm mostly interested in.
-
Some experienced testers who own these three .357s (Windy City, Rainstorm, Tactical) and have shot them side by side report that the Rainstorm power seems a bit higher than the other two.
Here is one interesting thread. Check out "jvc"'s post at the bottom:

I will get me a Tactical Sniper in .22 when Pyramyd starts to import the carbine version

Would you care to share some details about the carbine version? Like total length and barrel length?

It looks just like a shroudless version of the normal gun. The shroud is pretty much useless anyway in 9mm and even in small calibers a proper LDC beats the heck out of a 25mm shroud.
-
Thanks for the video. I think I'm becoming an Evanix fan. I'm looking forward to hearing more about the Tactical Sniper as GTA members get them and start using them.
-

It's probably based on the basic Rainstorm mesures with the barrel being 17 " ( talking .22 and .25 now ) instead of the 18.5" of the long Tactical Sniper, with about 5" of Baffels, Neil Clauge makes a great LDC that screws directly on the shroud
-
the shroud on the Sniper is a joke. purely for looks (it does look good) the air can't get behind the muzzle and there is only about an inch and a half of air space from the muzzle to the bottom of the brake.
it's 95+ db's in stock form. (I'm at 70 db now)
I'm going to fire lap it this weekend and probable degas it next week and install a de-pinger, may take a good look at the valve assemble while it's apart.
may even do some rkr type mods to it and then tune it over the chrony
-
same as on the Rainstorm .357
Different on the Small bores

My personal preference would be to ditch the shroud and use a LDC that screws directly on the barrel. The shorud flexes a bit due to the o-rings so a LDC on the shroud is more likely to clip the pellets and requires bigger holes in the baffles. A A&M Marksman would probably work real well on one of those small caliber guns.

Printed up a single shot tray for my sniper, going to fire lap it and didn't want to mess up my magazines or mess around trying to feed a bullet by hand into the barrel.
Should also let me shoot some longer bullets like the 105 gr semi-wadcutters
(http://i82.photobucket.com/albums/j249/dogwoodtheone/evanix%20sniper/632ECDF0-1213-4A53-A44B-6FB7F761FCAA_zpsjdhqy9ux.jpg) (http://s82.photobucket.com/user/dogwoodtheone/media/evanix%20sniper/632ECDF0-1213-4A53-A44B-6FB7F761FCAA_zpsjdhqy9ux.jpg.html)

Like your single shot tray wish I had a 3d printer just can't afford too many new toys at once still stocking on new AG's and periphals
-
A piece of aluminium, hacksaw, file and drill work just as well. It takes a bit more time but is much cheaper than a printer:

I notice that sniper has no cover for the hammer guiding pin and it's slot. That's something to keep in mind if you go hunting in the woods, it's easy to get some dirt in there which might affect the hammer operation.

Yep that works just as well and is indeed cheaper than a printer :D

that was one of the first things I noticed when I took the gun out go the box, going to have to see if there is something I can do about it with out making things to fugly or permanent
-
fire lapped the gun today, 10 each grit. seemed to help the accuracy a bit, time and rounds will tell.
Decided to try and tune it a bit, started shooting over the chrony
I had taken the hammer and spring out for a cleaning and debarring after the initial time over the chrony, I thought I had screwed it back in about where it was when I disassembled it.
First series over the chrony this time said otherwise.

still not what I got the first time, the action is smoother but I've lost some power.
any one have the barrel O-ring size? I think I'll replace mine, the gritty fire lap compound probably didn't do it any good.
suggestions and ideas are all welcome
-
I changed the O-rings in my barrels and If I remember correctly I used 10mm x 2mm wall
Those numbers are bad, the more you screw the spring in the more power, you must have put something back together wrong
-
Thanks NP, I suspect you're right.
-
I pulled it apart again, the only thing I noticed was the the guide pin when screwed in fully binds the spring, if I back it out half turn or more the spring is free to rotate.
Hammer still seemed a bit gritty so i polished it up some more. I'd like to polish the area it rides in but that is hard to reach and I don't want to gunk up the trigger mechanism
Going to make up a tool to help me get that thing back together a screw driver just doesn't cut it, major pain in the butt
-
I think you might have the hammer spring turned around. Take it out and flip it around. I know it sounds trivial, but the spring on my storm pup was binding also when I reassembled after installing the depinger. Not sure if the sniper is the same, but worth a shot.

My Blizzard had a spring that's similar at both ends. Have you checked that your barrel is aligned to the transfer port? While you reduced the spring tension you introduced a power curve while the peak power didn't change, I'd suspect a restriction somewhere in the air path. How about the valve housing, could it be upside down?
A leak is also a possibility, swap the barrel o-ring and check that the probe goes deep enough to seal on that ring.
-
I turned the spring around on my .357 and it's the same
-
measure the spring, same on both ends.
rkr haven't taken he gun that far apart yet, will have to check the port alignment.
the only thing in mind mind that would account for the change is the spring getting bound up by the guide pin
need to put it back together and send some rounds over the Chrony
Need to get a light setup for my Chrony so I can shoot in less than ideal conditions :o
-
;) Harbor Freight $3.95 each battery powered led lamps. Mount on top of diffuser with a rubber band so for $8.00 you have workable light source . I have been using this for my beta master with no errors as long as alignment is correct. Much cheaper than actual light kit for the chrony

Sweet! Thanks Don ;D

found a coupon from HF for those lights, $2.59ea, no sales tax here so walked out with 2 for $5.18! 8)
can't wait to try them out, thanks again Don :D
-
;D Glad to help and they work great with my Beta Master

Just had an explosive valve dump!! :o
I had polished up the hammer some more and made delrin washers (thin) for the spring to ride on, seems most of the "gritty feeling" was from the spring.
screwed the adjust back to flush with the receiver, shot a mag over the chrono had same poor numbers, shot another at 4 turns out, better but still kinda random
had just sat down with it adjusted 6 1/2 turns out, fired the first shot, looked ok, second shot was a blank, the mag hadn't moved, fixed that and BAMM! stupid loud and butt load of air hitting me in the face :-[
cocked it back a bit and there is no sign of the valve stem! ???
looks like my bad numbers where due to a failing stem.
at this point I haven't opened the valve area yet, but i have drilled holes in the shroud.... not sure what PA is going to say or do.. guess we'll see.
ears are still ringing
-
DANG, glad you were not hurt. Live to shoot again.
-
Got a call from PA, rifles going back for them to look at fix/replace.
Guess we'll find out in a week or two

Good luck on the return PA is pretty good about returns and hopefully they will be understanding with the replace or repair

Evanix seems to have a big problem with their valves. First one local guy with a .45 snapped the valve stem at the o-ring groove. Then I broke the valve seal, admittedly after some tuning leading to increased power. Bad seal thing also happened to two other local guys in both 9mm and .45 guns. Then I received a replacement valve and the stem in that valve started expanding so badly that it locked open after only 10 shots also dumping out all the air. So, it seems that Evanix has at least a batch of valves with poorly hardened valve stems and that they use a valve seal material that can barely handle the power levels of those guns as they come out of the factory.
What they should do is to redesign the valve without the o-ring groove having the seal in the stem tunnel instead. Then use better valve seal material and finally pay careful attention to their QC in stem hardening process. Things being as they are now I wouldn't buy another Evanix gun, these are not isolated incidents but they seem to happen with way too many new guns.
-
they seem to be pushing a little too hard and putting things out that aren't quite up to snuff, the hammer on my gun still had lots of burrs from the machining process, one piece had broken loose and was trapped in the spring.
Hopefully they get it together before their rep is tarnished too much.

they seem to be pushing a little too hard and putting things out that aren't quite up to snuff, the hammer on my gun still had lots of burrs from the machining process, one piece had broken loose and was trapped in the spring.
Hopefully they get it together before their rep is tarnished too much.
That has also been the case with guns here. Also the slot where the hammer guide screw rides seems to be chewed on several guns. Add to that holes drilled some 1mm offset blocking flow or breaking o-ring grooves, valve springs bouncing around and blocking air inlets, no depinger, unpolished trigger surfaces ...

I had 1 of the .357s for a year and the other one for over 6 months, shot many 1000s rounds out of them and they are just fine, maybe sometimes guns are best left alone :) :)

That is quite true, unfortunately not that many guns fill my exceptations as they come from the factory. The only ones that required no fixing (in my opinion that is) were my Feinwerkbau 300S and Anschutz 54. Besides, you've had trigger jobs done on your guns :)
-
only on the pup, the rifle is bone stock :)

Just got off the phone with PA, they're going to send me a new valve 8)
Quicker than sending it back and gives me an official OK to crack it open LOL

I glad to hear you haven't had any issues, the part that failed on my gun was left alone.
My gun had issues right from the get go, "gritty" action and poor performance.
The only thing I did was deburr the hammer and polishing it, along with fire lapping the barrel, none of which should have caused a valve failure.
I not saying all Evanix rifles have issue, but obviously they are sending some out that do. Which tells me they might be slipping on QC. Which I contribute too trying to get too much out to quickly
Look at how many new guns they've announced in just the last year.
Every manufacture has issues once in awhile and it has to be looked at like that.
It's only when the bad reports start out numbering the good that you can say that an issue has gotten out of hand and even then it might not be as bad as some will try to make it out as.
-
They probably do need to revise the material used for those stems, they are new to big bores so they still need to learn and feedback like yours is great and should get to the company as fast as possible.
Yeah, no matter what company, there's always lemons, boy you continually hear of lemons on them 2000+ bucks guns so nobody is immune to that.
The gritty action is one thing that should have raised an immediate red flag, that lever action is butter smooth and that is one recurrent comment that you hear
-

That is very true My first Rainstorm had a cracked stock and was replaced by the seller imediatly but the side lever was buttery smooth as is the action on the .25 replacement and the .22 I just received. I am Happy with both Rainstorm II's and am looking forward to a third Evanix big bore as soon as I have all my support equipment in place ;D ;D ;D
-
If I had been smart and not so eager to get shooting I should have called and gotten a replacement
But the thought of waiting several more weeks was too much LOL
I have a real problem with instant gratification :o
-
That's why I think the Pyramyd 10 x 10 program is a must, I always get it.
that gun would have never made it out of the store and for 10 bucks you woiuld have gotten and shot a good gun on day one, well worth it IMO

the receiver looks beautifully done
found more burrs and this:

either the port was drilled off center or the o-ring groove was machined in the wrong spot
You can't see it in the photo but there are more burrs inside the valve and the o-rings had a bit shaved off
-
Stem broke right at the o-ring groove, I couldn't find the other half :o
(http://i82.photobucket.com/albums/j249/dogwoodtheone/evanix%20sniper/375F4161-4C0F-4F28-8C51-4761D159B6A6_zpsfanc52sj.jpg) (http://s82.photobucket.com/user/dogwoodtheone/media/evanix%20sniper/375F4161-4C0F-4F28-8C51-4761D159B6A6_zpsfanc52sj.jpg.html)

Also look at the valve seal, it has been compressed almost to the cup part. I bet you'd be having a leak in a hundred or so shots had the stem lasted. That valve housing outlet hole being offset is also a familiar thing. although my gun had that hole in place while the transfer port was offset. I can't help but wondering what the heck is wrong with Evanix? They have a nice bigbore concept here and they are just wasting it with some poor design choices and poor QC.
-
is your valve seat flat? mine has small lip around it, almost like an insert was put in, metal color is different ???
-

The seat has a lip but it's all blacked out so I don't know of material differences.
-
Why is there an oring on the stem? It just weakens the stem and is not necessary if the valve is made properly. In fact, an oring will hinder performance here...I've tried it.
-
I have the feeling that I will end up making my own valve
And once my lathe is back in shape and probably a new valve assembly
-
cleaned my barrel again while waiting for the new valve, was finding small metal shaving on the patch, assuming it was lead.
Cleaned up the edges on the transfer port, smoothing out the transition
Lead in looks like it was cut with a chisel, spent some time polishing that up.
Will spend some time polishing the bore where the hammer rides as it still feels a bit gritty and rough. :-\
popped in my de-pinger since I have the gun apart.
-
spent an hour or so polishing all the moving parts, cocking action is now much smoother
Valve arrived today, hope to get it and try it out soon, 2 1/2 feet of snow on the ground right now though :o
putting in a lighter valve spring and trimmed the hammer spring down bit added delrin washers in hopes to let the spring move freely

You could even leave the valve spring out if you want it real light. If you have dremel you could smooth the edge at the valve housing where air turns from valve stem tunnel to the outlet. That's the worst bottleneck in a stock gun.
-
Thanks rkr
pumping so no valve spring at all is out ;) the spring I'm putting in is lighter ad shorter
Actually I already did that, have a nice diamond ball burr and rounded off and smoothed the port as much as I could, then sanded and polished and well
not as smooth as I'd like it ( hard to get in there) but huge improvement over stock.
I had also added some more holes in the block around the inlet, thinking of getting a conical spring and really opening up that portion
-

I've been thinking of a conical spring as well but you would have to make one yourself as ready made ones do not fit. Instead I've considered making a cross shaped support from a plate that holds the spring in the middle while still allowing a larger hole to be used for more flow.
BTW, can you actually pump up that thing from zero psi? I tried it in my blizzard and the gun didn't seal.
-
I've pumped several Evanix from zero, just have to cock the hammer.

Good point about cocking the hammer. ;D
Guns 2/3rds back together and holding air (no hammer spring 8) ) got it to 100 Bar before calling it a night

Yeah the conical springs I've found so far would need some "massaging" to fit.
I've also been thinking of a way to support the spring after removing most if not all the material the blocks the path
was thinking of drilling a small hole just before the threads for a small rod and printing up a spring guide, something that would hold it without blocking the path too much.
-
Well, my pressure test without the valve spring is failing, down to 80 bar now. It seems that PEEK really needs some additional pressure to seal. When the gun gets empty I'll make a spring support and post some photos in the 9mm tuning thread.
-
Finally got chance to finish pumping it up, still only partially together, decided to shoot a few more Lap rounds through it and want to be able to clean the barrel properly
Fire 5 round, 5th stuck in the barrel about 2" from the muzzle, made an odd sound - the air was slowly escaping around the bolt
had to hammer it out with my cleaning rod, pumped it back up and fire one more, not sure what happened.
I am running a lighter spring on the valve and trimmed the main spring a couple of loops.

Does your pellet probe (the thick part) actually reach the barrel o-ring? Sometimes the barrel is too far ahead or probe too far back and there's no proper sealing at the breech end of the barrel.
Also, the problem you have sounds a bit like mushroomed valve stem end which prevents the valve from opening fully. If I were you I'd open it up to check that stem. The new stem I got was like that and it eventually locked the valve open.
-
Bolt seals nicely in the barrel o-ring.
I'll take a look at the valve stem, hope that's not the case - I will be most displeased >:(
-
Well, it took me 8 shots to lock it open - you've fired 6 now. The speeds were all over the place with those 8 shots so that might be your problem. There's at least one bad batch of Evanix valves out there and some of the replacement valves are bad as well.
-
Hmm, this thread is a good warning for me to stay away from evanix... so much money for a gun with so many problems ... what a shame! Looks awesome though!
Post some groups when you can please!
Cheers!
-
LOL, if you look at it that way than you'll never buy High end rifles like Edgun, FX, Cricket,......those have by far more reports of failures, I tested a friend .25 Cricket and it was a true lemon, Edguns and Crickets rods are breaking left and right, FX guns are leaking all over the place and those are 2 GRAND guns,...it just Happens ;) ;)
Percentages is what it's need to look upon, How many trubble free rifles out there there is, Evanix has a pretty darn good track record :)
-
I've got an FX Cyclone, about 2000 shots or so down the way and problem free :)
-
Exactly my point,
I have 6 Evanix and had one of the originals, with probably 10.000 rounds each down the barrels, all problem free :) :)
FX is probably the Brand that you hear has the most problems overall, All kinds of problems with the Revos, Indipendence, now the Bobcats,....still can't say you'll never buy one, it's all about percentages :) :)
-
Two Evanix Rainstorms for a long time, shot a lot, no issues.
-
if you read the forums you will find that just as many problems with the evanix than the FX if not much more. Personally, I would get a FX any day before a evanix. Don't take me wrong, I think they are great hunting guns. I would never put them a par with an FX on accuracy (Generally speaking). That does not mean that there are very accurate evanix out there.
I guess I'm also biased because I find most tacs and Bullpups (no matter who makes them) to be the ugliest things around. Just happen that evanix make lots of them. :)
I guess I would go saying statements about any gun or gun brand without real data to back it up.
daniel
-
Of course FX is a better gun than Evanix, nobody has ever tried to compare the 2, but, again that's the point,
Man you go back and FX is gotta be the one brand with most problems, but than again all brands have problems, from The Indy to now the Bobcats is almost a weekly report, that don't make them a bad brand
-
I would never, ever nor I ever did put Evanix on par with Kalibur, Edguns or FX,....just saying those guns that are twice the price have all kinds of problems too, probably more ;)
-
I do realize, and this goes for any application, when you increase the number of parts and movable parts there is a significant increase in chances for any of those parts for malfunction. This is mostly for the indy, on the bob cat I can't really say anything because I haven't follow it.
I personally prefer guns that are simple just for that same reason. A Leaking gun is a problem that happens to every gun manufacturer. The moment you add orings, which are easily damaged, you open the changes for a leak. One of the reason I have hundreds of orings on my parts box. They fail. Many time you will not know that you cut an oring until 500 shots later with it fails. This is true for a $200 or a $2000 gun. I would think that it is easier to damage an oring in a $2000 just because the tolerances your tighter. So when inserting parts they are easier to damage. Just a though, I could be completely wrong.
-
Check post # 10 on this thread my friend, it's no O-ring , LOL
http://www.gatewaytoairguns.org/GTA/index.php?topic=61841.0 (http://www.gatewaytoairguns.org/GTA/index.php?topic=61841.0)
You just come out with an O-ring rant when nobody mention any O-rings, Indy tons of problems and the extra parts isn't an excuse, Revo, boy I read tons of threads about bad revos, Edguns valve stems, and all kinds of other bad parts, Cricket broken stems,...man the Cricket .25 my friend had was utter Junk.
bottom line is you cannot judge a rifle from one lemon when you have 1000s perfect functioning rifles out there and that was my point, wheter it's FX, Edgun, Cricket, Daystate, A.A. ( boy I can link a thread where those last 2 where mentioned with serious malfunctions ) or Evanix.
It's percentage again.
-
Please read carefully before you come out with your opinionated responses. I specifically mentioned that I have follow the issues with the bob cats so I can not mention it.
Now that I read the post, I completely agree that the failure or poor manufacturing is inexcusable for any manufacturer.

Amen, I'm glad you mention this because I would hope that you would start practicing some time soon, when you refer to many manufacturer that are not in your graces!
One last thing, I was talking general on the o-rings issue, if you did not notice. Or maybe I should of said seals and not o-rings.

When any machine is modified to produce more power, breakages will occur. Ive been buildings jeeps and 4x4s for years and saying that Jeep built a bad product because your lifted jeep with oversize tires broke an axle while rock crawling is not fair. Saying you will never buy an evanix rifle because you read about one that broke while someone was trying to modify it is the same thing.
-
Well said Rescue. I agree with your statement completely.

Yep once mods are made all bets are off, however, in the case of my gun it was bone stock and unopened and the valve seem failed after less than 300 rounds.
Does that make all Evanix rifles bad? no. Does it show a lack of QC? not really. does it show that all manufactures can have issues? most likely.
as manny has stated its all about the numbers and nobody but PA and Evanix have those. I would expect if the QC was that poor that PA would stop caring them as they would become unprofitable. time will tell
-
No excuses for Evanix but I'd bet the pressures of delivering the new models it taking its toll on them. If you've seen any video of their facility they appear to be quite small and not super neat in the workplace. That said, my RS2 is going on two trouble free years and has a nearly flawless finish inside and out. I love it more each time I shoot it :)
They have an unique position in the PCP hierarchy with a loyal following, that is an earned position and I'd expect them to hang on to it without too much issue.
Tom
-
Couldn't agree more Tom, said a similar thing earlier, I suspect a lot of the issues we're seeing its from growing pains and trying to expand a bit to fast.
any growing company will have these issues, how well they handle them will be the important factor
-
Well for the kind of money they are asking for these rifles (Evanix, FX etc...) i would expect no issues with warranty repair and/or replacement. Any experience?
-
PA quickly responded to my issue and sent me a new valve, I suspect if I hadn't already modified the shroud I could have sent it back for a replacement gun.
Someone else in another thread was in contact with Evanix directly and was pleased with their responses, haven't heard how it turned out yet though
-

If you buy an Evanix from Pyramid, my experience is that they will bend over backwards to help with any issue or questions that you have - including unquestioning replacement or repair of anything that needs it.

If you're trying to bring Maurader/Crosman into the mix,....well, that's an all other cup of tea . LOL ;)
-
You are sure stock on the crosmans. My point was to follow your own advise. Don't put other guns down just because they don't fit you "personal view".
-

Man, that's funny how maurader owners try bring up stuff on threads that have nothing to do with it, LOL
I would discuss that on an Other thread since it don't belong here, I sure never brought up or mentioned any comparisons with Maurader/Crosman on this thread ;) ;)
-
I though we were talking about FX(other high end guns) having a lot more problems than more more evanix. lol. I most of mis understood.
I just thought that your statement was to far reaching as far as problems with guns. I do have to say that it is great that Evanix has PA behind them and not AoA. :)
I can see that this will not go anywhere, so I will not highjack the thread. Sorry guys.
-
Bolt seals nicely in the barrel o-ring.
I'll take a look at the valve stem, hope that's not the case - I will be most displeased >:(
Did you find anything? I had a completely new valve made without the o-ring groove. It doesn't use more air and now I know that it won't break at an inconvenient moment.
-
nope didn't find anything, stem still looks fine.
Ran another 25 rounds through it yesterday without a hitch - still not sure what happened on that one.
was still finding shavings (though smaller) when cleaning the barrel so I smoothed the port area some more and polished the leade as well
while looking in the barrel I notice something that looks like pitting :o there is a "ring" about 2" in from the breach
I'm hoping to get a chance to fire it over the Chrony today and do a bit of tuning, then 50 yard accuracy tests
it's using a lot of air right now, 5 shots take it from 200 bar down to 130ish
-
Way to much air, should get +/- 7 shots from 200 BAR to 150 BAR
-
OK played with it a bit today, with a weaker spring on the valve and 3 coils cut from the main spring adjuster turned in till flush with back of receiver I got the following string using JSBs

And cleaned up the outlet a lot, smoothing and shaping - also smoothed the transfer port and leade in
now to see if the improved consistency translates to improved accuracy
-
not an expert in reading numbers, but it looks pretty darn good to me now :)
-
worlds better than before, went from a 127 fpe to 142 fpe gun way more consistency and actually tunable.
juries still out on accuracy... last shot of my sight in I had a baffle clip - first time thats happened in several hundred rounds.
printed up a couple of replacements but tried to get fancy, think it hurt more that it helped - printing some more simpler ones now.

Dogwood, this has been an interesting thread so far.
Do you mind briefly summarising what changes/fixes you've made to the sniper so far...?
-
NP, Deburred the hammer, polished all the moving parts, replaced the broken valve, added a few more holes to the valve intake area, used a diamond ball burr to smooth and round the valve port area, did the same for the barrel port area as well.
I had to trim the length of the hammer guide bolt as it was catching the spring. I replace the valve spring with a slightly shorter and weaker one, I trimmed of 3 coils from the main spring and made ACETAL washers for it.
I've also fire lapped the barrel.
Almost forgot, I also had to deburr where the pressure tube retaining screws come thru on the receiver, they where shaving the o-rings on the valve

If you want a bit more a 6.5mm transfer port (+ barrel and valve housing openings) will get you to 150 fpe. What we need next is a source for stiffer hammer springs, the stock one is horribly soft and long and contributes masses to the hammer bounce.
-
I might start looking for more power once I get the accuracy where I need it, right now it's not there
Consistant valve opening should help, have to see how the new baffles do and then think of what needs done next.

Baffles? Do you mean for the shroud? There's just too little volume in there for it to make any real difference.
-
I have a AR6 shroud on my .357 that is 3 1/2" longer thn the regular shroud, I have 5 baffles in there and it does make a difference,
I than Have a 6" Neil Clauge LDC, 2" actually overlap the Shroud so it's only 4" longer than the end of the barrel.
overall noise difference is significant
-
I added a bit to my shroud

OK, that WILL make a difference. Is that 38mm pipe or larger? I'll have one made of 50mm pipe.
-
Yes, it's a 1.5" tube (38.1mm)
50mm would be pretty nice
And it does make a huge difference back yard friendly with it on 8)

Holy cow ! ..you're not afraid of drilling new guns, LOL
Seeing the sorts of results you guys are getting from a bit of hands-on machining, I think I'm about to pick up a second hobby. Guys like tofazou (and other guys here on this forum) seem to get quite a bang for the buck modding these guns with a little straightforward hands-on machining.
It would be great if someone put together a "basics-you-need" list of machine tools/essentials for an airgunner.

You can do a lot with a mini lathe and some basic tooling such as micrometers and dial gauges. I do suggest a copy of "Machinery Handbook" and "Machine shop Practice' vol 1 and 2.
Projects like valve work and even some barrel modifications (like chambering and crowning) are do able. Although I do recommend getting the largest lathe you can accommodate and afford. If you get serious you will end up with it anyway. Better quality equipment is also easier to learn on.
All together you can get into that hobby for around $1000 to start.
If you want to do breeches and the like you will need a mill and its setup equipment. That's where things start getting expensive.
-
Thanks - sounds good, I'll do that. I still have all 10 of my fingers, so I'll keep a healthy respect for this stuff, and educate myself with those books.
-
Ill second everything Rescue35 said.
I really wish they had the Grizzly G0607 around when I started, might have gone that route instead of the mini lathe
the Mini lathe is a great way to learn, but you quickly out grow it.

did some 50 yard shooting tonight, 2 clips worth of JSBs and 4 Hunter Supply 95gr HP .358s
JSBs where running about 3-4", not good. I had sorted out a 5 HS 95gr HP the day before and lubed them, did not weight them at the time (I generally don't weight my pellets)
I sorted them based on looks, some of those bullets looked like Sh$t. on a whim I decide to weight them, 4 where within .1 gr of each other the 5th a good bit off.
Fired the 4 that where close
(http://i82.photobucket.com/albums/j249/dogwoodtheone/evanix%20sniper/9DF0942C-58E4-4BC8-963F-96582CA8BE3A_zpsiy1h3imb.jpg) (http://s82.photobucket.com/user/dogwoodtheone/media/evanix%20sniper/9DF0942C-58E4-4BC8-963F-96582CA8BE3A_zpsiy1h3imb.jpg.html)
tad over 1" ctc and yes there are 4 hits, 2 pellets almost went in the same hole. Picture is side ways, 1st and 4th shot are together 2nd was low I think and 3rd to the left.
it was also slightly windy with gusts, shows some good promise.
So I sorted the rest by weight, trying to group them within .2 gr I then sorted some JSBs, I'll see if it helps them or not.
More testin to be done, worlds better than when I started, almost minute of a rock chucks head 8)
-
JSB, unsorted at 50 yards should group .750
You should cover your group with a quater
-

This one defiantly isn't, going to try some sorted and see if it helps or not
-
shot some more at 50 yards, sorted JSBs didn't do any better than unsorted, also the HS 95 gr HP sorted didn't do as well this time. I only sorted by weight perhaps I should have sorted by weight and condition as some look pretty bad. Will have to try again.
25 yards I get nice grps and hit what I aim at, it's only when things get stretched out a bit that it all goes away.
Will have to run a few more sets over the crony to see how consistent things are, might need to work on that a bit more.
Considering putting new crown on the barrel as well, if all that fails I might get a LW barrel or a TJ
on the off chance something will happen I sent an email to Evanix.

Not trying to sound know it all but I don't remember seeing if you checked for the pellets clipping the baffels
-
I did have a pellet clip the baffles once, I've since printed new baffle with larger bore opening, so far I haven't seen any indication of baffle strikes.
Printed baffles really show a strike too, you can't miss it even if its a light one.
I might just try some grps again without the shroud extension on and see if it makes a difference , can't hurt.
-
Clean the barrel real good, touch up the crown and remove the shroud. If you keep the shroud check the barrel band alignment. That should get you going. In my blizzard I took of the shroud and used a 18mmx4mm o-ring to center the barrel to the band.
-
thanks rkr I'll give some of that a try, can't completely remove the shroud as is used to hold the stock forearm in place. ::)
I'll try cleaning the barrel again and see if that helps, I've notice what looks like pitting in the barrel about 2" in, not sure what effect that might have on accuracy.
will shoot some grps without the extension I made and perhaps without the muzzle end guide, let the barrel float.

You could try both floating the barrel and then stuffing a big o-ring in between the shroud and the barrel. That should tell you whether the barrel wants to be supported or not. My BSAs with 15.5mm floating barrels are real good shooters so I see no reason why a gun with 18mm barrel wouldn't like to be floating.
-
One more thing, shooting big bores is completly different than shooting small bores, the kick does alot to the accuracy, it took me awhile to figure that out years ago when I 1st started shooting the Sam Yang .45 and the Career .357
You gonna learn how to shoot them big bores, more like a springer in a ways than a small bore PCP.
I've seen a ton of people getting all excited abot big bores but when they got them couldn't shoot them accurately and sold them blaming the gun, gotta learn to shoot them guns ;)
-
its rarely the guns fault! 99% of accuracy comes from the shooter, even a gun with a bent barrel can be shot accurately if the shooter knows how :)
-
You gonna learn how to shoot them big bores, more like a springer in a ways than a small bore
Interesting point, I'll give it a try and see (luckily I do own a springer and know exactly what you're talking about)
The shooting posistion is very different at 25 Yards than 50 might be a key factor
-
just shot a 4 shot string with a free floating barrel ("dang" is it loud, my ears are still ringing)
what I saw was vertical stringing, about 4" first shot 4" low from POA, second about 1" higher third 2" higher than the second and the fourth right next to the first shot
all where about within a half inch of each other left to right and along the vertical point of aim
Thinking that my valve is not opening consistently and my speeds are varying too much.
Will sit down and run some more over the Chrony (with my can in place, my ears and the neighbors will be happier)
-
Shot a few more strings over the Chrony before the pump gave out (4 year old Benjamin, time for a rebuild I think)
any who first string JSB's
870 200 BAR
873
872
864
853
empty shot
816 145 ish BAR
second string
883 200 BAR
872
868
853
823
816 150 BAR
I made no adjustments in between those strings.
as a reminder this the first string I got with the current settings
860 200 BAR
874
881
882
empty
868
857 150 BAR
looks like something is moving, things breaking in? looks like its time to re-tune
going to put a order in at McMaster for a number of uncut springs (20") so I can play with length and strength (and maybe some peek too)
none of those strings would explain why I'm getting the vertical stringing I am or the side to side movement.
I tried shooting the gun "loose" like a springer and it still performed poorly
at short range 25 yards or less it will make one big hole, stretch it out to 50 and it looks like &^^&
(http://i82.photobucket.com/albums/j249/dogwoodtheone/evanix%20sniper/0881A464-5964-4D9A-9108-E538DF07736E_zpsz95zqkbu.jpg) (http://s82.photobucket.com/user/dogwoodtheone/media/evanix%20sniper/0881A464-5964-4D9A-9108-E538DF07736E_zpsz95zqkbu.jpg.html)
one inch squares, aiming for red square
looks like it likes a free floating barrel, I just need to figure out this vertical stringing
-
Those strings look just as if someone had increased the hammer spring tension. Since spring tension doesn't increase by itself I'd suspect something is wrong with the valve. If it's valve seal or stem is hard to say and I have trouble figuring out how they could cause that change in the string.
It looks like your barrel doesn't like to be free floating. A sudden change in accuracy after 25 yards would point to pellet instability. Usual suspects are barrel crown or clipping.
-
at 50 yards you should cover your groups with a Quater, velocity difference sure isn't the problem, ( nice string BTW )
I'm still going with operator error :) betcha as you learn to shoot the gun groups will tighten considerably
-
sorry rkr that last post was a bit misleading - the group picture was with the barrel tight and me trying to shoot it "loose"
here is the group from the free floating barrel
(http://i82.photobucket.com/albums/j249/dogwoodtheone/evanix%20sniper/EE304673-2C0C-46FE-B2A6-7DFBEE06132D_zpspw3mbmux.jpg) (http://s82.photobucket.com/user/dogwoodtheone/media/evanix%20sniper/EE304673-2C0C-46FE-B2A6-7DFBEE06132D_zpspw3mbmux.jpg.html)
the 2 bottom holes are the first and fourth shot, the third is the highest
as you can see the side to side movement is very small but the vertical moving is great, which leads me to believe a free floating barrel will help.
Once I get my pump back up and working I'll try a few more things to try and narrow it down and verify.
still leaves me with what looks to be a valve issue. Might order some peek and make a new seal, can't hurt, but I think part of the issue is the valve outlet cutting into the o-ring groove.
update - place an order at mcmasters for some springs and a peek rod
-
I assume that you have checked that all the pieces in your scope mounts are tight. The shot string doesn't explain that 3" up and down movement. I also doubt that free floating the barrel would do that, although you could stuff one big o-ring in between the band and the barrel to make it semi-floating and see what happens.
BTW, after being a pump guy for 5 years I finally gave up and got tanks with my 9mm Blizzard. It just takes way too long to fill one up when you let the pump cool down and all that trouble for just 5-10 shots.
-
I believe Manny is right about hold technic with big bores, why, because I also had a problem just like you. Rounds all over, then would group a clip or so then all over again just like your pics.
What I found out in the end on my Windy City was it was suffering from excessive barrel vibration most likely because I had it putting out 127fpe which is hard to do vs a rainstorm . What I did was: 1. Make sure barrel/bottle band was not putting any pressure on barrel and tight screws carefully . 2. Put thin low recoil rubber between bottle and shroud. 3. Placed two o-rings on barrel between it and shroud. 4. Made sure to rest riffle at its balance point or held at its balance point on bags with butt planted in shoulder. From there it started making one big ragged hole at 50y.
Must say, befor I came to a understanding of what was going on, I went thru 600 JSB, sent the hawk scope back for warranty work (nothing) wrong with it ;D order a leapers, bugged W. Piatt and cried the blues :'(. Everything's fine now, so hopefully one of those things will help you just remember in ways hold technic on big bores is just plain different from little bores good luck.
-
...most likely because I had it putting out 127fpe which is hard to do vs a rainstorm
Just for more info for us tuning-interested guys, do you mind explaining the details, and your own experience - what was hard about getting 127 FPE out of your .357 Windy City? What specifically did you try, and where/how was it hard to do?
I thought that the Windy could hit 127 FPE pretty easily. In fact, Aussie was tuning his Windy down to try and get around that level - so I'm really interested to hear what your experience was.
-
Was not hard for me my exhaust port was opened up a little. Some gun just naturally come high strong. The rain storm has a straight line to valve where the bottle guns have the 90 angle it goes thru so it makes harder to get fpe. For me just cranked hammer screw in 1/4 at a time and try different fill pressure. Now don't get me wrong I could most likely crank it all the way down and get 130-140 but it would waist so much air :( I get two full clips now

You're rittght about the shot string, I was expecting a lot more variation than I got.
We're thinking along the same lines, I replaced the muzzle piece that fit snugly in the shroud with a couple of o-ring
I had the pump working for a little bit last night, harbor freight orings are probably the issue now, got some coming from McMasters
I'm a desk jockey, I need all the exercise I can get and I hate the gym, plus I can use it as leverage on the CFO when I want more guns ;)

Not ruling it out, I'm sure it is a factor, the issue I think with this gun (or part anyway) is the barrel is fixed too well, it is solid with the shroud and the shroud is fixed by the barrel band and the forearm piece used the shroud to hold its self in place
There are multiple issues at play here and no one simple solution
-
All of my Rainstorms have a solid Barrel to everything else fixed, no free nothing just solid.
My Sumatras, Sam Yangs and Careers where solid barrel fixed to air reservoir and breech, no free floating nothing.
All guns superbly accurate
-
Not saying what I did will work for everyone just seam to settle my barrel. As far as Aussie he had one of the first batch I believe in the WC so quality control might have been better, you know portholes alined properly. Also with him using air and tempture over there, altitude , yada yada yada. Will increase or decrease your fpe. Also noticed I was clipping shroud end and baffles I opened end cap by a 1/16 ditched the baffles and now sport a Neal C. Which for me makes it shoot a hair better. Sorry for kind of jumping around but am at lunch and juggling sawn itch and chips :P

and my .22 marauder is free floating and I can shoot a rock chuck in the eye at 50 yards, what's your point?
I can stack pellets at 25 yards with my Gamo springer, again what's your point?
you've never had a valve stem break, yet I have, again what's your point?
your guns don't use the pressure vessel and shroud to hold your stock in place either, this one does. Is that a factor? I don't know yet.
I'm looking for answers to problems and harping like a fan boy isn't doing anyone any good
I'm not saying the way the gun is being held isn't a problem, but I saying it sin't the only problem
if you'd looks at those strings you'd see that the velocity has changed with no setting changes. and guess what? consistence is the heart of accuracy, whether it be how you hold it or how the valve opens to how the barrel vibrates.
I'm glad your guns work great and are accurate, still doesn't do ME any good.
oh and my shooting buddy has a 3D in 357 and we aren't seeing any of the issue I'm having with mine
-
Yeah and the 3Ds have the stock holding the shroud and barrel all together too, and both mine are fine,
Jim Chapman's video of the tactical sniper shows normal evanix Standard grouping.
Maybe you should have shot the gun for a few 100s of rounds before starting to mess with it, that way you would have known if you got a lemon, ( which can happen with all brands ) now you'll never know if she was or you just messed the gun up somehow,.....now you'll never know.
-
the only thing I did before the valve broke was mod the shroud - and I did shoot several hundred rounds through it. so yes a lemon - it happens :-\
but you're right I should have waited to mod the shroud so could have sent it back - but now I own it and I'm trying to fix it. ::)
But when I spend that much on a gun I don't expect that to be the case- its called Quality control...
I'm looking for ideas and suggestions and some are doing just that.......... 8)
-
If the accuracy was that bad you should have sent the gun back immediatly.
-
they won't take anything back that has been damaged - i.e. what I had to do to get the shroud extension mounted.
and I was hopping that the accuracy would improve as it broke in, which is the case for many air guns.
I needed to make it backyard friendly so I could shoot it........

Have you tried contacting Evanix? I sent them a few emails and they are sending me a new barrel(due to port alignment issues) once they get the export license they must apply for before shipment. The guy/girl was very helpful and assured me that all guns were tested for accuracy before leaving the factory. The problem is they only test the .357 for accuracy at 18 meters which to me isn't much of a test at all. Of course this has been a week or more ago and I haven't gotten any shipping conformation emails so they may just be blowing smoke up my a**. Guess I'll find out soon enough.
As far as accuracy my groups looked similar to yours but after learning how to shoot the gun (my first big bore) for a while and refilling every 3-5 shots, as well as correcting a few shroud/barrel alignment issues my 50 yard groups (3 shots) can now be covered with a quarter. Now after Will gets his hands on it I should be set for 7+ shots.
-
I did and them an email about 4 days ago, haven't gotten reply- that is very encouraging that they are willing to send you a new barrel, hopefully it get through to you soon
and your right 18m isn't much of a test, at the range (hair under 20 yard) I can shoot one largish ragged hole
glad to hear you're getting it straighten out, hopefully once I get my pump rebuilt I can get back at it and get rid of some of the variables.
I'm starting to think it might have something to do with the forearm stock arrangement, going to try shooting it with it resting on the receiver and not the forearm - see if that changes the dynamics at all.
after my last chrony session I realized my tune had changed, need to back it off again and see ....
-
I'll say this again,
Sumatras, Sam Yangs and Carreres have the barrel stuck to the airtube and they are suberbly accurate,
other videos of Sniper Tactical show good accuracy, I think you are just chasing ghosts
-

Now don't get me wrong I could most likely crank it all the way down and get 130-140 but it would waist so much air :( I get two full clips now
I get two magazines from my tube gun and I'm not done yet. Although getting 3 magazines at good power level is probably out of reach. What's your fps spread for two mags?
-
All of my Rainstorms have a solid Barrel to everything else fixed, no free nothing just solid.
My Sumatras, Sam Yangs and Careers where solid barrel fixed to air reservoir and breech, no free floating nothing.

There are two o-rings, one holding the shroud against the barrel and another holding the shroud against the band. I wouldn't call that solid.
-
I'll say this again,

Not very valid point as they have double airtubes making the structure much more rigid. Shooting with support on the receiver is agood idea as it will eliminate a lot of things like standing wave vibrations in the airtube. Your gun does ping quite a lot doesn't it?
-
Still, don't think the the stock being the problem, just looking at the pictures is't not any worse than a MAX or Stormpup
-
I know this may not be a ideal solution to your problems, but why not just send the gun to Air Venturi for repair? Imo your past the point of receiving free replacement/parts, I know it not worthy to hear but thats just the way it is..... on the other hand worst case scenario it will cost you $100 bucks from Air Venturi and you will get the darn gun shooting like it should :P. Just my .02 cents....

Haven't seen Jim's video, will look for it, also the 3D stock is one piece, completely different from the sniper, the forearm is not attached to the reciever in any way, all the wieght of the gun is on the air tube and shroud.
Watched Jim's video, only 20 yards and very comparable to what I see at that range and I'm not even using a rest at 20 yards
-
Query sent to Air Venturi to find out what my options are, thanks again for the idea

Jim just told me he was getting 1" 3 shot groups at 75 yards with his.

Yeah, I mean I know that the more custom builds like the late Haley, XP's, corsair, Sinner's ect. are super accurate. But 1" at 75 yards from a widely available BB that can be had for less than $1000 is awesome imho.
-
I take 1" at 75 yards with a .357 any day of the year :) :)
-
right now I'd be ecstatic for a 1" groups at 50 yards :-[
-
Aside from Unrepentantsinner with his Haley .257 (which is technically not "big bore"), real groups I've seen posted (with calipers) shot by big bore owners of Extreme, XP, etc don't get much better than that
-
At Jim's suggestion I tuned the power down, I used a weaker shorter main spring and tuned it to shoot 1 magazine from about 740-770-740 from 140 BAR to 110 BAR using JSBs
Initial 50 yard test is very encouraging.
Going to pump it up again today and shoot it tomorrow, if it does as well or better than I know I'm in the right ball park.
Then I'll try to tune it up some more and see where the accuracy falls off.
sorry picture is rotated, blue box is on the bottom of the target, as you can see 3 shots went into one large hole and the left and right outliers where most likely me ( didn't rest enough be fore going out after pumping)

whole group is still under 2" which is about 2" better than what I was seeing before.

Also got 8# of ballistic products buckshot coming, hopefully the gun like it as well...
any tips on shooting those?
-
load them from the front of the magazine

Thanks NP, flat side in our out? or does it matter as long as it s consistent?

No flat spots on the "Ballistic Product" 000 buck .360 roundball

From the picture (and I could be wrong) it looks as though you're measuring the left edge against one furthermost hole to the right edge of the other furthermost hole - to get your group size.
Since you're using digital calipers, you might get some more accurate group measurements if you measure from the left edge of one hole to the left edge of the other hole. In effect, you are currently enlarging your group size with the calibre diameter (which is something for a .357).
Another way to measure would be centre to centre. This can work well with digital calipers: just place the measuring point of the caliper in the respective centers of the two holes that are your farthest in the group.
This might give you smaller groups without tuning ;)
-
Still, at that distance even at 850-900 fps it should be one rugged hole the size of a quater
-
Indeed. That's what we'd like to see.
When/if the single ragged hole happens (knock on wood), then you can measure the group size by measuring the widest diameter of the hole, then subtracting the calibre (in the same units - inches, whatever).
-
no testing today, de-gassed the gun to look at something and when I went to pump it back up I get a nice Hissss
valve isn't seating - tried the heavier spring hoping that would help - nope no go.
got to figure out how to get it to seal
-
How do you degas them ? .....just shoot them down ?

If your valve isnt seating the first thing to try is pumping it with the hammer cocked so that there is not that pressure on the valve, if that doesn't work you should keep it cocked and while pumping have someone gently tap on the valve area with a rubber mallet or the like to coax the valve into seating.
-
Thanks Caleb good tips, luckily I remember it from before and had the gun cocked.
after putting the heaver spring in I didn't even mount he pressure vessel to the receiver I just started pumping.
I'll try the tapping trick next
NP, I shot it down to 100 bar then pulled the tube from the gun and used a small brass hammer to lightly tap it until it was completely empty, thought the brass hammer would give me more control and abuse the vale less than the steel hammer hitting at flu speed every time.

You could just slightly open the hex nut at the side of the valve block to degas.

One more thing, shooting big bores is completly different than shooting small bores, the kick does alot to the accuracy, it took me awhile to figure that out years ago when I 1st started shooting the Sam Yang .45 and the Career .357
You gonna learn how to shoot them big bores, more like a springer in a ways than a small bore PCP.
I've seen a ton of people getting all excited abot big bores but when they got them couldn't shoot them accurately and sold them blaming the gun, gotta learn to shoot them guns ;)
What are you saying Manny? :o
-
Just because is a PCP people think thay won't kick, than they get them and immediatly realise that they actually kick pretty good compared to the mellow 30 FPE .22
because of the low velocity -/+ 900 fps the bullet/pellet takes a long time to exit the barrel making correct shooting technique a must.
alot of folks freak out because they can't immediatly shoot groups like they do with the .22 PCP and sell the gun because it's inaccurate
It took me awhile to figure out to shoot Big Bores, luckily I never had a Small bore PCP before so I wasn't shocked by the difference, I went from a Supermagnum Springer straigth to a Career Ultra .357 and a Sam Yang .45
-
Basically, a good follow through is a must.
-
well between being sick, pump giving me a hard time and getting the gun to hold air I haven't done much. I did get to try out some of the Ballistic Products 360 round balls, got 2 sessions over the crony before the pump acted up again,
shot the 3rd and last season for accuracy at 25 yards, not good, 2" c-t-c about what I was getting with the JSBs at 50.
they do load nicely and are a good cheap practice load, so not a major bummer. Will see how they do in my friends 3D.
Once I fix the pump I will try changing the breech o-ring again, size is 012 (got that from PA, assuming its Metric)
-
now I definatly think you got a bad barrel, there's no other explanation to get those bad groups
-
I'm leaning that way as well, thinking of ordering a 24" TJ in .357 ;)
-

LWs work also well, some local lads are getting 15mm ctc groups at 60 yards using bullets. My stock barrel does 4mm ctc at 20 yards with JSBs and 8mm ctc with roundballs. I think I'll have to work with the barrel next.

That's good to heat rkr, the LWs are .356 are they not?

I don't recall that but make sure it's not choked if you plan on shooting bullets. Have you checked that your "brake" is not clipping? Howabout the crown, that's another easy fix unless it's tilted or offset.
-
Definitely not clipping and the crown looks pretty good.
Was thinking of trying to redo it anyway but my current setup would make that difficult.
I'm thinking the lead in might be too long if not irregular as well, will try and check that tonight by hand searing a pellet
On my friends 3D you can feel the bullet as you close the action where on mine you can't
-
Maybe your barrel is vibrating , maybe your barrel band needs pressure applied or less pressure. I use the barrel band as the final adjustment when zeroing on my WC. With scope if it hits high/low/right/left on a 1" target at 50y I use barrel band set screws if need be to make it hit dead center if scope will not .
Just a suggestion , works for me maybe this can help your groups

Interesting thought, I will have to explore it a bit - can't order a new barrel for a couple of weeks anyway.
I know on my Marauder that if I tighten the end cap too much it will affect accuracy, lots and lots of variables - need to figure out a way to weed each one out.
-
took the barrel band off, first grp was at 16 yards, one large ragged hole, promising. took it out to 25 yards 2"+ still :P a couple went into one large hole, so I tried again, concentrating on my form, loose...follow through...
bah no better, still over 2"
still seeing a good bit of leading, going to run a bunch more fire lapping bullets through it, can't hurt at this point.
still a few more things to look at before I write off the barrel completely.
-
Assuming your shroud setup is similar to the rain storm you might want to check shroud alignment. When you slip the shroud through the barrel band and over the end of the barrel things shouldn't bind. Now where I found an issue was when I got the shroud down to the breech where it screws onto the breech. The shroud wouldn't slide on to the breech threads without pushing down a little (pushing the shroud towards the air tube). That means when I was putting the shroud on the barrel was being lifted up in order for everything to align. Not sure if you can understand what I'm saying, it's not easy to describe. I took a .1mm shim and placed it in the end of the breech under the barrel. I tried a few different thicknesses but this one got me lined up perfectly. Now when I put my shroud on it lines up perfectly with the end of the breech and screws right on without any vertical persuasion needed.
I did this as well as remove a bur from the barrel transfer port and my groups (after lots of shooting and learning how to shoot a big bore) are able to be covered by a quarter at 50 yards. The gun was a pain in the butt for a long time but after you get it dialed it's a pure joy to shoot.
-
I understand exactly what you're saying C.ALLS as I see pretty much the same thing and reflects what I'm seeing, using JSBs I'm getting good groups at 25 and 50 yards AFTER I removed the barrel band. I'll have to give your shim idea a try
here's a 50 yard grp of 7 shots I just did, strong crosswind from light to left, tried to time it between gusts
(http://i82.photobucket.com/albums/j249/dogwoodtheone/evanix%20sniper/9ABE58F3-4B1C-4EE7-9653-71B563B9F1B0_zpsufuqkalf.jpg) (http://s82.photobucket.com/user/dogwoodtheone/media/evanix%20sniper/9ABE58F3-4B1C-4EE7-9653-71B563B9F1B0_zpsufuqkalf.jpg.html)
shot 6 and 7 reflect what I was seeing on the Chrony, rapid drop in velocity after 5. shots 2 -5 are about 3/4"
I'm going to assume 1 was either me or the wind since it is vertically lined up with 2-5
seems the guns not real happy with the Round ball past 16 yards.
If I can duplicate theses results later (hoping the wind will calm down) I'll start shooting over the Crony again to see if I can't bring the velocity up more without affecting accuracy.
-
dogwood, I don't know your crony string but it seems that you could back out your hammer tension a few turns. It would lower the velocity of your first shots and conserve some air pressure for the last two. Might even the vertical stringing some.
Are the major grid lines one inch?
-
Thanks Tom, yes the major lines are 1"
I haven't gone back to trying to tune it better yet. This is just where it was when my pump started acting up.
-
Pull up the two lower shots up and you have a decent group with some horizontal stringing possibly due to wind conditions. Your are getting close.
Interesting about the barrel band, shroud and tube alignment. I happen to be working on a rainstorm receiver today, before fitting the new barrel I decided to spend some time checking the geometry on the CMM (coordinate measuring machine). The bore of the barrel and valve block are in perfect alignment with the bottom surface of the receiver. The barrel bore has and angular misalignment of 0.0001 per inch with the sides the receiver (horizontal) which is very very good for a commercial product. The method of threading the shroud to the receiver is very rigid, I really don't see a need for a barrel band in their design and will probably open up the shroud clearance of the band on on this rifle so it does not touch the shroud. The Sniper may be different but the overall design seems very similar. I guess my point is, with the rigidity of the shroud I don't see the flexible barrel forcing the shroud out of alignment. More the other way around.

-
Sounds like you have access to some fun tools Tom :D
You make a interesting point about the shroud and barrel and most likely I will do what you plan on doing and open up the barrel band. Right now it's just hang in off to the side out of the way.
C.ALLS did seem to have success shimming, which means he was able to bend the shroud with the barrel, doesn't seem like he should be able too but he did ???
-
I just found this, It may shed some light on C.ALL's and your's issue. It may not be the barrel that needs shimming but the shroud is not square like mine.

interesting find, went and checked mine, nope not my problem.
My barrel slopes downward at the muzzle, the gab between the reservoir and barrel gets smaller. :o

Pretty sure you don't get what I'm saying which is understandable as it's hard to explain. See if this post from the other thread helps.
"When you screw down your barrel stops on top of the breech you're pushing the barrel down to rest on the bottom of the breech bore. I put my .1mm shim at the end of the breech bore between the barrel and the breech which raised my barrel end and aligned it with the shroud. You'll notice when the barrel set screws are loose the barrel to breech clearance is rather large and seems to get tighter down towards the transfer port. My shim raised my POI down range as well and allowed my scope to be adjusted closer to it optical center. "
-
forgot what I was doing and replaced the spring - shot some over the crony and tuned it up a bit.
Much windier today with swirling winds thrown in.
Tuned it to spit JSBs out a bit faster - little over 800 fps

shot at 50 yards, last shot (7) is in the lower right, not sure what happened there. really seeing a difference with the barrel band removed.
-
ran a last minute before dark grp. backs up the previous grp I do believe
I did all the adjustments before shooting, 2" up and 1/4" left - which in my book means things are getting very repeatable.
I think I missed labeled the outlier - 6 I think is really 5. Not sure what happened but I'm going to blame it on me, same for 1, that was a quick shot.
Still really windy, these guys buck the wind pretty good - shot 7 is out of frame - but I was aiming at something else and the pellet went right where I was aiming

You've got a lot of patience!
-
You've got a lot of patience!
LOL, been thinking the same :)
-
Looks like your gun is starting to group, is this without the barrel band and shroud now - free floating barrel? I also got some fliers on my 20 yard tests, 4 shots in about 1mm ctc / 10mm hole and then suddenly a flier that opened up the hole.
-
NO barrel band, but is with shroud and my extension.
-
well it's trying my patience :o
cooler today but little to no wind. Groups were bigger and I had more fliers.....
looked at the barrel and it was leading pretty good, so I decided to clean it, this is what I found:

Mind you this is the second patch through, the first had even more on it but was so dark I couldn't get a clear picture, those are lead shavings. I had found them on the previous cleaning and rounded the edge of the port inside the barrel, apparently I either didn't do it enough or there is someplace else shaving the pellets.
I rounded the port some more and polished the heck out to the leade in. I then ran several patches with grit from my fire lap kit, med. then fine and finished with JB - much smoother and shiner - we'll see if it stays that way.

Have you tried loading those pellets straight to the barrel and not using a magazine? That would eliminate one potential source where pellets could get shaved.
-
Good idea rkr, i'll use my load tray tomorrow and then check it after shooting a few rounds
-

Post some results, I'd like to see what effect the barrel cleaning and polishing had. If it groups well with the tray try some groups feeding from the magazine to check if that's your problem, I just realized that I was feeding JSBs from the magazine when I had those flyers ... come to think of it - a simple reason could be that the magazine is just not centered right in the middle.

I didn't find any shavings after shooting with the tray, haven't check yet after shooting with the mag again.
need to shoot a grp with the tray and see if anything changes.

Have you checked the crown in your barrel? I tried pushing a pellet through and it got stuck on the crown indicating that the crowning tool has expanded those ends of rifling a bit. I did a small recrowning job but haven't been able to test it.
-
Visually the crown looks good. on 2 occasions when I was doing some fire lapping I had bullets get stuck about 1" from the end of the barrel, well before the crown.
I'll try manually pushing a Pellet through the barrel and see if I can feel any rough spots.
-
tried to shoot some more - 3+" to the right of aim - took 2 shots and said no more.
So I pushed a pellet through the barrel, reasonable smooth until about 1" from muzzle, then it got really hard - like it was choked. Was hard until pushed all the way out.
here's what the pellet looks like
(http://i82.photobucket.com/albums/j249/dogwoodtheone/evanix%20sniper/PushThru_zpsaee3c32f.jpg) (http://s82.photobucket.com/user/dogwoodtheone/media/evanix%20sniper/PushThru_zpsaee3c32f.jpg.html)

-
Yep, that barrel is junk,...... Pyramyd should send you a new one.
-
I agree, just sent Boris another email explaining my findings and my opinion of the barrel >:( I was polite though ;)
hopefully they do the right thing.
-
they are usually really good like that, send the pictures too
-
I attached the same photos, helps get the point across
-
That's bad. Do those scratches come from the muzzle or when the pellet enters the rifling? Mine has a tight spot at the part where the thin part of the barrel ends and then when the pellet dome comes out of the barrel it gets stucked requiring good tapping to come out. I think I'll get a 9mm brush and some polishing paste and try to loosen up those tight spots.
Edit, if you look at the pellet skirt you can see your source of inaccuracy. Those rifling marks are deep enough to cause lips at some points of the skirt. When the pellet leaves the crown it tilts as one side is still touching the rifling while the other isn't. I had slight lips in mine but I managed to get rid of those by lapping the lead in and the tight spot on the rifling. You might still be able to save that barrel if you don't get a new one. Wrap some cloth around a bronze brush, smear on some fine valve grinding paste and work on those problematic spots. There's clearly a machining burr somewhere causing that damage to the pellet and I'd suspect the lead in to rifling as you have lead spread on both sides of that mark.
-
Boris at PA/Air Venturi has forwarded my pictures to Evanix, waiting on a reply from them
-
Just got the word, Evanix is sending a new barrel for me.
Oddly enough they also confirmed the 9mm barrel is choked :o
-
Choked! I thought the .357 barrels were un-choked and slug rated. When J. Chapman was testing the first .357 he made the statement they can also shoot cast were lower cal evanix could not? What's the deal.... A Chang from original barrels?
-
I was really surprised by that as well, why on earth would you choke a 9mm? :o
Would explain why the JSBs worked the best
-
I've heard from an Evanix person (and several other sources also) that the 9mm barrel on the Rainstorm is unchoked. So at this point there is conflicting information from different sources. I think before jumping to any conclusions, the best thing is to wait for more concrete evidence. I like evidence-based approaches to things. At this point, who knows?
-
Based on the magazine design of these guns, I expect that Evanix has designed them to primarily shoot pellets. I wouldn't be surprised to find a choked barrel.
Tom
-
Don't the Sniper .45's and .50s have the same magazine design though?
-
Don't know but I hope they gave them some additional length.
-
Same magazine, not really longer (relatively speaking). Evanix advises against using longer ammo for those guns too. So I think the choked barrels issue is still up in the air.
-
well, first thing I'll do when the new barrel arrives is push a pellet through. No idea why they would choke the barrel for one gun and not the other or vice versa
-

Mine has a tight spot where the barrel diameter is reduced so it fits the breech. Another tight spot right at the end of the barrel under threads. I think those are caused by careless lathe operator but the fact is that I get poor accuracy with bullets. I really wouldn't want to waste money on LW barrel but that might be the way to solve things.

I will most likely order a TJ barrel later, going to make it a bit longer...
I'm hoping the new barrel will give me good performance so I don't have to do it right away

Aren't Sam Yang barrels tight on both ends?

Been reading this thread a day or two now. I am thinking of ordering this version of the sniper. Who tunes them aside from Will? I was planning a hunt in a month or so and I know Will has a pretty long waiting list. Can the bark be tamed? Anyone making shrouds? Thanks

Get a .50 cal and you should be good with power without any tuning. A shroud is pretty much worthless in these bigbores as the barrel is too thick, what you want is a high volume LDC. There are threads at the end of the barrel, although they are not always straight.

Neil Clague makes an extremely effective LDC that screws onto the shroud and it even overlaps it so overall length is reduced, my .357 with am 8" + 2" overlap makes the gun very,very quiet
-
Well, I went with the .357 to keep the cost of the rounds down a little bit. From what I have read and the folks I have talked to I feel this rifle will take hogs at the ranges I am wanting. It should be here any now. :-)

Sent an email to Boris last night and got a reply this morning, he has my barrel and is forwarding on to me soon, hope to see it in a week or so

Got my barrel today - first impressions not good

yes it is two tone ???
looked through the bore and looked much better than the original. cleaned it well and pushed a pellet through, choke seems closer to the end of the barrel and the pellet came out clean. (nicely cut rifling)
checked port alignment and it looked good.
fired one shot from 15 yards to see if it was in the same ballpark as the other barrel - looked good so I took it out to 50 yards - hmmmm
(http://i82.photobucket.com/albums/j249/dogwoodtheone/evanix%20sniper/73c4f0ec-a58c-4aa5-80c9-46b5a1264d9b_zpsee4d25b0.jpg) (http://s82.photobucket.com/user/dogwoodtheone/media/evanix%20sniper/73c4f0ec-a58c-4aa5-80c9-46b5a1264d9b_zpsee4d25b0.jpg.html)
POA for first shot was center lower target - all others where red square - I did adjust the scope after the first group hit low consistently - added enough clicks for 2.5" up :-\
too early to tell yet, need to put more rounds through it - oh and these where JSBs - squares are 1"
-
Unless you get a rugged hole it's no good, anything less than one single big rugged hole is substandard
-
I was thinking about the difference of how I shoot at the different yardages, was trying something different at 50 yards, seemed to be helping

But after the fifth shot I started hearing a hissssssssss coming from the breach >:(
time to take it apart again, I suspect my reservoir will be empty by morning. ::)
-

I agree with you Manny, After getting one hole for 14 shots at 55 I am happy with my barrel. I hope the issue with the thread starter gets fixed.

Have you cleaned the barrel properly, checked the barrel crown and barrel band?
-

yep barrel was filthy and took a good deal of cleaning, crown looked pretty good and the barrel band is out of the picture altogether
have to deal with the leaking valve now

The barrel flexes quite a lot without the band, the breech is just not strong enough. I made a delrin adapter to center the barrel in the band and managed to do a 5mm ctc group with bullets at 20 yards. Not the best but there's some promise there. In my tests leaving the band out seemed to cause more flyers.
-
I'll try it with it back in place once I figure out what the *(&^ is going on with the valve. :o ( I think you predicted it's failure a while back ) Might just have to make something
-
I would bet my money on damaged valve seal or bent/mushroomed valve shaft. I've had both in my gun.
-
Printed up a single shot tray for my sniper, going to fire lap it and didn't want to mess up my magazines or mess around trying to feed a bullet by hand into the barrel.
Should also let me shoot some longer bullets like the 105 gr semi-wadcutters

How did the single shot tray work out for you? You want to sell one?? I want to be able to single load my sniper with longer pellets and or cast bullets. Let me know. Thanks
-
Tray worked very well, bullets drop right in.
be happy to make one for you, hows $15 shipped?
I can make them in Black, Blue, Red or white.

What holds it in? And yes 15 shipped works fine for me.

friction, it fits fairly tight.

well second valve is toast >:(
seal material is so deformed that the metal valve "cap" is touching the valve body with minimal pressure, I verified it with a multimeter. :P
My friends 3D is still working well, I know Evanix is capable of making good guns, but mine seems to be a major lemon.
Starting to get a bit tired of this. :-\

It kind of not worthy doesn't it - but you should think positive, at least you haven't encountered the bent sidelever yet. Evanix has rather decent design here, I just have to wonder why they have to flush it down the toilet with poor material choices and QC? Kind of makes me wonder if I should have waited for .35 Cricket instead.
Edit, as a first aid you can turn the seal around, it will work and will probably last until you can get a proper seal made for the valve. For the seal material PEEK works and PET-P is what I use currently. PEEK is a bit harder so it requires more precise surface to seal. You might also want to consider making a new proper valve without that o-ring in the stem.
I've had two Korean made guns now and nothing but poor experiences. I know I'll steer clear of anything Korean made from now on.

Hey dogwood,
Now that you have a multimeter :) would you mind taking some dimensions and making a quick sketch of the valve? I'm curious if the Tactical Sniper is running a larger poppet and the larger area is crushing the seat or they just have a material problem. You can use my valve drawing for reference.

Tom,
here's my valve drawing, did it in mm's but added some notes on with inch on that part that is different - hope you can make sense of it.
Made a new valve seal today out of PEEK (got my lathe working well finely) hope to try it out tomorrow. 8)
-
Finished pumping it up, popped the valve once - hissssss >:(
pumped it back up a bit more and loaded a mag - shot 7 shots, can't hear the hiss anymore 8)
set it down, going t eat dinner and then check the pressure- hopefully is stays the same ;)
-
still had a really slow leak, put another mag thru it and that seems to have taken care of it, that PEEK is hard! :o
Just when I think the barrel is going to be good it throws a couple off in the weeds, it is an big improvement over the other though.
it's shooting well enough I think to allow me to see if it is me or the barrel.... :D
-
well, I think we all know how it went :o
first mag was hitting 3.5" high at 50 yards, adjusted 2" down and shot the second mag, first three shots went to the same place as the first mag? added another 2" down, 4th shot was 1" high and slightly left, 5th shot 1" low and 1" right, 6th shot 1.5" low and 1" right
7th 3/4" high and slight left :-\
third mag, no idea where the 1st shot went., second was 1.5" high and 2" right, 3rd was 2" below that, forth almost in the exact same hole as the second, fifth .5" left of 3rd. 6th .5" low and .5" right, 7th 1" low and. 5" right (-all JSBs)
think I'll stick to shooting round balls at 25 yards and save the JSBs until I can get a SeanMP-TJ barrel

If you get the TJ liner barrel let us know how it works. I'm considering going the same route myself.
BTW, are you sure it's not your scope that's the problem? Also, have you checked the barrel band and associated support system for binding?
Edit, I forgot to say one of the lads here tried 9mm LW airgun barrel in his Evanix and is now looking for something more accurate.
-
well considering the things I've seen the scope might not be out of the realm of possibilities - was just trying not to think about it....
Will probably explore the scope possibility for a bit, if it proves to be OK I might just get a carbon tube to put on the barrel before I make the leap to a TJ.

After comparing notes, it seems that the valve in the 9mm Sniper is the same as the 22 cal. RS with the exception of the poppet, throat and exhaust port diameters. The area increase of the cap that holds the seal is 24%, this raises the closed force at 2900 psi from 385 to 503 lbs. This is significant in terms of the compression on the seal and added energy to knock open the valve. In the case of the Sniper's Delrin seal, assuming the sealing surface is .025" wide, this gives an area of .035^2" @ 503 lbs force = 14,371 psi stress in compression. Considering Dupont puts Delrin's compressive strength between 8,500 and 10,700 psi, it's no wonder these valves are failing.
Tom
Edit:
I also looked at the o-ring groove in the valve stem. The reduced diameter is 2mm or 0.079", this is only and area of 0.005^2" ???. Applying the 503 lbs required to knock open the valve at 2900 psi, the stem material would need to have a minimum yield of 100,600 psi :o (no SF included), making both the material selection and heat treatment absolutely critical! There is NO defending this design, even with tool or CM steel the fatigue of repeated hits will eventually cause a failure ::).
-
Edit, I forgot to say one of the lads here tried 9mm LW airgun barrel in his Evanix and is now looking for something more accurate.
if I understand correctly, the Lad was not impressed with the LW barrel either? LW is a 1 in 16" just like Evanix?
Tom

Put on a different scope, something I had laying around.
Here's almost $4 worth of JSBs shot from 50 yards ( the 4 shots near the center of the target where from the first string and at 20 to makes sure we were in the ballpark)
didn't do anything between strings except pump and reload the same magazine

Going to put my other scope back on and stick with round ball at 20-25 yards, at least until I can afford to put a new barrel :o
-
Now I don't even think it's a barrel problem, I just don't see 2 barrels in a row shoot worse than a Shotgun when there's so many accurate .357s out there, gotta be something else, why don't you try put that barrel on your friend Stormpup just to make sure ?

Looks like I do have a scope problem too, put the original scope back on and it wasn't taking adjustments at all. At first I though the gun hated the round balls, now I know it was the scope ( shot the last of my JSBs, already ordered more should be here next week)
It's a konus so it has a lifetime replacement warranty 8)

Tom
To quote/translate his words "It's not a bench rest quality barrel". LW is 1:16 while Evanix is in the 1:18-20 range. LW makes also 1:10 9mm barrels, I don't know if they would be any better or worse.
-
Evanix .357 Rainstorm barrels are 1:16.5" twist rate.
I strongly suspect the .357 Blizzard is the same barrel twist, but I could be mistaken.

Here's one individual stating 16:1 http://castboolits.gunloads.com/showthread.php?216386-Help-to-design-FP-for-RS-II-in-9mm (http://castboolits.gunloads.com/showthread.php?216386-Help-to-design-FP-for-RS-II-in-9mm) I remember reading 18.5:1 somewhere but can't find it now. Jussi is a gunsmith and said 20:1 but of course could have made a mistake in his calculations. I just got my barrel perfectly placed so I'm not going to take it out for counting.
BTW, a new agricultural loading lever for my Blizzard is nearing completion. I also got some good tips on strengthening the stock one if anyone encounters the bending problem.
-
I'll measure that rate myself one of these days - but I'm inclined to trust WP's numbers. He's pretty precise (16.5), indicating some care in measuring, and also his number converges with what some other gunsmiths have said too.
I'd be keen to hear any tips you have about strengthening that side lever...

I measured the twist rate in my Blizzard at 20:1.
-
Interesting. If that's the case, then it's even less likely then for the over-stabilisation theory to be relevant to your issue.
I wonder if Evanix is putting different barrels in the Rainstorms and the (or some) Blizzards - because it seems unlikely that Will Piatt and other gunsmiths who have measured the Rainstorm at 1:16 collectively all made the same mistake. Could be different barrels in those guns.
My days are so packed now that I haven't even touched my guns in weeks, but I'll check my RS when I can.

It seems that .357 Recluses also have 20:1 twist. Kind of makes me wonder how many barrel manufacturers there are in Korea and if any of those airgun manufacturers actually make their own barrels ... Those barrels also share the threads at the muzzle, I used LDCs made for Sammys in my bigbore LDC test and they fit Evanix perfectly.
-
Evanix makes at least two different barrel twist rates in the .357. I have two .357 Evanix barrels and there is no doubt they're way different twist rates.
-
My replacement Konus finally showed up, got it on and hope to play with it a bit this weekend. Simply haven't had the time or inclination to mess with it lately
-
Looks like I'm going to have to shim this one, ran out of vertical adjustment and still hitting 4" low at 25 yards.
On the plus side the horizontal grouping was looking good
-
score a set of Burris Signature Zee rings to deal with the scope issue - so far so good, then spent some time shooting over the chrony before I for too tired to go on.
The barrel seems to be breaking in and the groups I'm getting are better than when I first tried it, need to bring the state of tune up a bit still as the drop at 50 yards is just too great
-
got a wee bit of PET-P for a new valve, best deal, but way too much LOL ;)

If you need that much to produce one valve, you must not be very confident about your building skills ;D They usually sell short pieces in evilbay.
-
Actually I need to do 2, so a I got a little extra ;)
my friends 3D let all its air out last time we went shooting, betting the valve is shot ( wasn't an explosive dump like mine was)

Check the rear of the valve block where the lever attaches if you get that explosive dump. It may have stretched a bit. Broken valve seal seems to be a rather common occurence with Evanixes.
