Update on the .30 rs. I’ve sent it off to have the ports opened up and discovered my “new” rs from PA had a valve that had already been opened to .203 complete with the marks from what looks like pliers on the valve. Probably why it came shooting so hot. The barrel port however was still at .195. Opened it up and now it’s pushing unsized 66 grain bbt at near 900 FPS which will put it at 925 sized to .299. I have a pair of Wilson combat flat wound springs, 17 and 20 lb, waiting to try in it when it gets back this week. I will run some chrony test with 50 jsb, the 60 grain fn and 66 grain and post . It will push the. 44.75 well over 1000 FPS now so a spring swap should bring those down to accurate speeds.

Hey Daniel! Got the RS .257 up to 986 fps/107.96 fpe with the 50 gr NOE RD today. This with the new poppet I made from the PET-P. Still playing with it, and the uncut spring you sent.

Man you’ve got that thing smokin! Nice to see that coming along as a repeater. I would love to have a .257. It just seems to be the ultimate long range caliber for a lot of different game. I like the power of the Texans, but not sure about the style of that rifle. So a repeater is really appealing.
Received my tracking number for the rs today. 2 day shipping so I should have it Saturday. Just in time for clear weather and some shooting time. Really hope the flat wire springs work out.

Now that is super nice in a traditional style rifle, IMO (ie not a typical manufactured repeater or direct flow system, not that there is anything wrong with that). The RS in most any caliber really has to be just the best in class (price, style, versatility, etc), IMO.

I agree. The more I shoot the .30 and my jkhan(rainstorm basically) all the positive attributes just keep adding up. Versatile, smooth sidelever, accurate with a variety of ammo and easy as a carry in the woods.
Rick has a 357 sniper that he has installed a .30 barrel and probe in. The 357 valve is larger inside dia than my 30. He’s pushed the 66 to 1025 FPS. No info on the curve, but the ports are .250. I like what Michael is doing on the .257 conversion, and am considering a conversion myself. I’m curious as to the difference in the valve size of the .25, 357 and possibly the .45

Wow, thats interesting. Less work to perform..........

Are the mags the same width, ie just change out the .357 for a .30 mag in this situation?

This has probably been pointed out/discussed, but sure Manny either knows off the top of his head or can just pull out from his Evanix air-mory

oneshot61 · « **Reply #68 on:** November 16, 2018, 03:18:08 PM »

Talked to Rick this morning, he doesn’t have a .30 mag, but said his 357 mag slid right into place into my .30. So I’m thinking the 30 would fit the 357.

So I have a few numbers although not definitive, still very promising and more to come.
Ports at .203 3k psi . Spring was preset.
.063 music wire spring cut to1/8 gap between the hammer and valve stem. Adjuster flush to the tube . 3000 psi, 50 grain jsb. 933,932,936,938,936,930,927.
1/4 turn in and nearly identical shot string with 52 grain eppug from Rick Morrill sized to .299. (the 52 are accurate. I’ve shot some 50’s that were not) This puts it at just over 102 ft lbs for 7 shots.
60 grain 854 -7 shot bell, same spring set
66 grain 825 - 7 shot bell, same spring set
Next test will be at 3200 psi with 50 jsb, 52 eppug, (pic below) 60 grain and 66 grain bbt hp. I will have a new spring,(pic below) ss,.072 wire cut to leave a gap for free flight. The goal is not max ftlbs or FPS, but max for 7 shots for hunting. Then detune with a spring for 85 ft lb with pellets. Haven’t tested yet for max cliff power.
Also my valve has not been radiused inside at the port. That will be on the next tear down. Should be good for 30 FPS or more according to RKR’ s findings on his Evanix??

Prouzy · « **Reply #71 on:** November 25, 2018, 10:05:36 PM »

Thats looking good! And at 3200psi, you might get a mag of the 66gr bbt up to 850-ish.

oneshot61 · « **Reply #72 on:** November 26, 2018, 12:44:44 AM »

Thanks Chris. Just going by the max @ 3k he text to me, the 60 grain hit 870 unsized. I hit 854 on my curve with this spring, sized. I think he hit 910 @ 3200 with the 60 unsized. Guessing? I’d say 890 on a curve with the 60 and 875 with the 66. I wish I had some 62 grain bbt from the noe mold. The bbt are moving much faster for their weight compared to the 60. 60 grain pic below.

OH, Man!!! that spring is doing the business!!! The spring you sent is doing well, but can't use it in free flight. this new one you have sure looks to fill the bill!

I decked the .257 mold further to throw at 44 grains.
Getting very good accuracy now. And decent, sort of shot string.

They look a lot like your Pic on the left. Only with the addition of a crimp groove.

Free flight would help this I think. Still working on different poppet profiles.

Toned her down to 915 fps, and it really helped for a 9 shot mag.

Looks like your learning a lot with this .30 Daniel!

Hey Michael.. I have that ss spring coming that may be just the ticket. I compressed this spring for about 6 hours, then cut it in hopes of no radical set under load. I’ll do the same with the new one. Heavy spring is the ticket for free flight and standard or mds hammer in this gun. I forgot to weigh my hammer when I had it out. The one in my .22 is 38.4 grains. I’ll weigh the .30 tomorrow night. Once I get a high, medium and low spring set up, the last two things will be an mds hammer and radius the valve... then I’m done🤠
Your getting 80 ft lbs on a nine shot string! That’s really good out of that gun! Is yours 250 cc? I would love a 300 cc tube to go to 3200 on this one. I have a kral 330 cc on my mega that may fit .. but no way I would take it over 3k. Another 80cc at 3k would be nice. Not sure if the threads are the same on krals tube as the Evanix valve. Evanix list theirs at 230 bar on their website. Only reason I’ll go to 32 on it. Probably run it at 31 when I’m through testing.

KnifeMaker · « **Reply #75 on:** November 26, 2018, 07:21:23 AM »

Daniel, I remember Travis saying one of the reasons they decided to not carry Kral was the tubes were not the same thickness in the entire tube. Thin and thick spots if I remember right. He didn't trust them.

Yes, the 250CC if I remember it. Wish I had the chance to get oine of the larger tubes Airventuri had for a short while. I think manny said 280cc's?

Wish this thing was a bottle gun. 500 cc's, WooHoo!!! No idea way PA quit carrying them. Would have been a natural.

Mr Lee says 3325 psi for the Rainstorm II's, sooooooo---

That’s a good tip. I had to do that to my fill port poppet. Put my poppet in a drill, shaved it with a new sharp chisel, then jb bore paste as I turned it in the poppet housing. Saved the day😉

Work is taking all my daylight hours lately, but I got about 30 minutes to run some testing with my new ss spring. My thoughts are that unless I’m shooting for one mag at high power with the 66 grain bbt it’s a bit to strong for a decent non peaky string. Even with nearly 1/4 inch free flight my spread is 27 with one shot in the middle causing all the problems. 908-937-899 FPS over 12 shots, jsb 50. It’s just pushing the hammer to fast. However.. I tried something quickly today and preliminary testing is promising. I inset a strong magnet into my stock, centered and near the back half of the hammer at rest. I think because of free flight it has a chance to slow the secondary hit to the hammer. I was able to get three more shots over a 900 FPS threshold. All testing was at 3050. Next testing will be with my 18 lb spring with the magnet installed. I’m looking for 14 shots over 920... hopefully..then take this to 3200 psi and test for a high power 7 shot mag.
