2000 psi fill guns

[Doug Wall]

They are made to be shot like match rifles. 
Taso

How is shooting a match gun different from shooting any other gun?  Aim and pull trigger.

Right.  You can do that with any gun.  The Challenger is approved to shoot in 10 meter matches in the sporter class.  That is why they are configured the way they are.

Taso

Ok that makes sense.   So I could not take any PCP to an event they have to be pre approved.

Match rifles typically shoot in the 600 fps range, 0.177 only. No optical sights. Certain size restrictions on gun size and stock configuration. You can look up the ISSF rules.

Thanks,  yes i am totally ignorant about any competition airgun shooting.   I just shoot for fun and to hunt.   

[RAJOD]

I am really close to clicking yes in my shopping cart.



Yes I have to have a sling.  My Daystate was too pretty to drill, but I think I am going to sling that too, just makes its easier to carry and aim walking around.

Its this or maybe get a range finder.

Ribbonstone,

You have said in the past that once you have an AA 200 you will compare all rifles to it.  Truer words have never been said.   

I love my T200.

I still haven't decided to bump up the power or leave it alone.

Rajod,

AA 200 over Challenger a million times!

No doubt the AA 200 is better for its purpose and quality too. 

But its $500.00+ vs $183.00 gun.

I go over to a buddies and we shooting targets, chipmunks etc.   Sometimes the air tank gets low.  mine gun really not good at 2000 psi.    But then could switch over and use the Maxiumus at 2000.  Plus say my tank is out I could actually use my dusty old hill pump to do 2000 psi if need.   Pumping to 3300 is no small feat.   

This crosman maxiumus sounds fun and almost a disposable rifle at 183.00.  From what I have seen its pretty accurate at 30 yards.

Don't even get me looking at that gun.  It is a very nice looking gun.  If I were to get that type for sure that AA 200 would be on the list.

I have a Maximus in .177 and love it. I only shoot for fun, but do most if it in the 50-60 yard range, it is 62 yards from my deck to the end of the fence where my targets are. At that range, using H&N Sniper mediums, I can get quarter size groups all day, dime size if no wind, off a bipod in the prone position. It also likes the Crossman Premier Heavies, but I tend to get a flier every 5 or 6 shots with those, the rest are usually touching. Pumping it with the Benjamin pump is a breeze, but I did break down and buy a SCUBA tank.

It looks like you have a stable of nice guns. The Maximus is a bit rough around the edges in some ways, but it is what it is, and for the money pretty hard to beat.

It has one thing many other guns don't have.  It shoots pretty accurate.  That is crazy how well you shoot with yours.   You should take your maximus to Extreme bench rest and beat all the fancy FX guns with it.   I bet the sponsors would have a heart attack and never invite you back .

[RAJOD]

Ok the deed is done.   I pulled the trigger on a

I think you'll be very happy. Here is a 5 shot group from about a week ago at a lasered 62 yards. My son was standing beside me on the deck shooting as well and he isn't the lightest on his feet. The one bad flyer was when he moved and bumped me. I love the .177 but thinking about adding another in .22 with a Boyd's thumbhole stock. As much as I like the looks of the Daystate Wolverines, I can't justify spending that much when I can get the accuracy and enjoyment for a fraction of the cost, especially when all I do is poke holes in paper in the backyard.

I totally agree with you on that.   You don't need a Daystate to have fun shooting or to kill a rabbit.   

I am amazed at how well your groups are with that gun.  Impressive!

I usually quit at 2900 psi and go to the scuba shop.   I'm thinking I might be able to fill that maximus 40 times from 2900 to 2000 psi on my tank.

One guy said he used a 3200 psi scuba tank and got like 150 fills on the maximus.    More shooting less driving for refills.

taso1000...this one is mostly for you.

Couple of "plugs" for the AA s200 or AA 200T.


I kind of rely on them for years as a base line foe what an airgun chould be able to do...something to fall back to shooting when I get to wondering, "is it me or the gun".

1. Consistent accuracy.
2. Consistent point of impact.
3. Long shot low velocity variation shots counts (For a non-regged rifle).

Tried and tried to get a definative answer as to wich is more accurate, the old .22 S200 or the newer .177 200T.



Darned if I know which really "wins" even after years of playing around; seems like they swapped places every other test.


Heres two sets of targets on on page...50 individual shots from the .177 and 50 shots from the .22, both at 20 yards against 1/4" circles.   NEither one missed at least cutting into the 1/4" circle.



Or a more traditional set of targets shot 5 shots per target (40 shots each) at the same 20 yard range:






Whatever the differences really are, its about 2/100ths of an inch in the last set of targets...even with 40 shots, all that really takes is one "oops" on my part.


If you have to have big-power in a PCP, pass them by...that's not what they do best. 

Adjusted, the .177 does quite well (efficiency/shot count) at anything from about 6 to 12 or even 15 foot pounds. The .22 seems does well from about 8 to about 16 foot pounds. Can certainly go a higher, but the shot count/efficiency goes to "carp".

If you have to have a repeater, there are add-on mag conversions available.  Not something I'd really care to do, but are folks who love the idea.

If you want to be really quiet, will have to add an LDC (certainly not the only PCP that needs that attention).

BAck to the original question.


An odd thought.


Regulated rifles, esp. if regulated to something like 1000-1200psi output.

So long as the fill pressure is higher than the regulator output, will get the full power of the rifle....just not for as many shots.  So if you had a rifle regulated to 1200psi, and it gave 80 shots when filled to 3000psi (1800psi of air use), it would give  40 shots (at the same speed) if filled to 2100PSI (900psi of air use)...or 20 shots when filled to 1650psi...etc.

Some mighty fine shooting!  Both of those guns look to be very accurate. 

I don't think I will be regulating the maximus any time soon.  Its just a light weight in- expensive fun gun.  I might even leave it open sights for rabbits. 

The only gun I've felt I had to regulate was that hatson, my others do pretty well without one.  But I understand what you are saying on how they work.  Thanks!

Being normally a big bore shooter,I went a totally different way with the Maximus.  I told myself I would not mod it. UhHu!

It took all of a week to wreck that plain. LOL

Valve ported, tp ported. barrel port opened. Interior of tube polished. Hammer polished. Trigger changed out and polished all surfaces. Polished bore and put a 1200 dollar Zeiss scope on it.

Well, injured my back, and cannot even lift my Big Bore 257. It weighs in at just shy of 15 lbs.

So I needed a full spectrum, (range) varmint killing lightweight ag. I heard of the accuracy of the Maximus with it's new barrel, and when I learned that it was just over 5 lbs. well the dye was set.

Well, the shot count was good for hunting. (20) good shots, but when I stretched her out to 80 yards, the bell curve became evident.

As I bought the gun for light weight, and accuracy, low fill pressure did not come into the picture. (have two compressors),

So I did the Magnum ss screw mod which chants the fill to 2400-2500 psi. Very impressive shot count. However, with higher fill, first shots were low due to valve being harder to open, and the bell curve remained, only more pronounced.

Added a Huma Reg, set to 15-- psi, and fill to 2400 and the shot string jumped up by 50+ shots. On the reg, for really flat shots, it will give 38 very flat shot string shots, that will keep the 18 JSB's under quater size group at 80 yards. Less that 1/4" at 30 yards, and 1/2 at 50 yards. For 40 shots straight!

If I mill the valve to hold two more ss screws, I can fill to a full 3000 fill, and go for over 60 flat shots.

Now I ask you, if you did not know the price or name of the ggum, would this sound like an entry level gun?

I've had ag's that cost well over 2 grand, and were no more accurate. Nor higher shot count, other than the bottle guns. LOL

Wouldn't mind adding a nice Boyds stock, as I feel the gun deserves it, however, there goes the weigh again.

Lates change, removed the 4x16x50 zeiss, and replaced it with a
6x24x56 Athlon First Focal Plane. Man I love a FFP Scope!

This little gun has been racking up quite an impressive list of varmint kills in its short life. More than paying for its up keep.

Only ones I have that are factory low-pressure fill are a .22 2K Disco (can manage 40 shots at 19.5 foot pounds), A Challenger PCP .177 (that can manage 65 shots at 11 foot pounds) and a 1.5K FDPCP (that can manage 20 shots at foot pounds).

Actually, I'm most impressed by what the FDPCP can do with so  little pressure...but that rifle has a bit of "internet-stick-on-it" due to one guy's (and only one so far as I can tell) experience.

HAve made any of the 3K guns into 2K guns with a bit of tuning at one time or another...the performance  (energy and/or shot count) decline as you are working with 1/3 the air (3K vs 2K)

I would be interested to know how you got your Disco to 40 shots at 19.5 fpe. I get 24 at 23 fpe with my Disco which is great for small game and longer range nutter elimination.

One of the reasons I keep two QB converted HPA rifle is that they shoot the same no matter how much over reg. pressure  they are filled.   Yeah, it;'s get to get 205 shots / 13 foot pounds, from a .22 QB 79 (call it a 900psi output). 

Basically it is 1 shot per 10.25 psi over 900.  So If I fill it to 1925psi, will get 100 consistent shots...fill it to just  1413 psi, would get 50 shots...etc.


Good way to drain a tank for about $200 invested (and don't write off a cheap QB/China made barrel until you test it...often you will be surprised at how well they do).

Yes good points on those constant shots.   I'm thinking the next gun I get will be ugly Big bottle gun with  a dial so I can go from 30 fpe to 12 for even more shots.   But I need another PCP like a need a hole in the head.

Actually probably getting a range finder next that sends hold over info to smart phone.   I like gadgets.

Phil, I use the gun any where from 19 fpe to 23 fpe, depending on what I am hunting. Either are just a small adjustment away.

I get the high shot count from the very dependable "Huma" regulator, combined with the higher fill pressure afforded by the mods I have made. The higher tensile screws from Magnum are were a great start for safety, along with full porting thru out the valve, tp, barrel, Removing gauge block for better flow to valve and fully polishing the tube for the hammer travel.

P.S. Screws from Magnum Air. Power Adjuster from Disos or us, springs from both Discos r us and Tim Hill airguns, and good advice from Restern here on the forum.

Considering you're wanting to use "excess" air (air at too low a pressure to work with other rifles) than a big bottle regulated rifle might make sense (would to me).  Use as much of that low pressure air as possible and get the most out of your tank you can, then have it filled.  Yeah...the filler really doesn't care if the tank has 1700psi or 2700psi left in it, it's pretty much all the same to him (or her).

Are scores of pages of post about HPA conversions to QB's...which will make for a kind of industrial-ugly, but cheap useful rifle.  Know I've been places with a QB conversion I'd never have gone if I had to protect a pretty rifle.
