Well so much for brand new BSA mk2 .....

Yes, I use the factory approved method of bottle removal.

At the moment TWO stacked 111 o-rings is holding 200bar of pressure which surprises the hell out of me. I just wanted to see if the bottle would go brass to brass with a second o-ring. The original o-ring of course, was dry flat and split on removal, but the o-ring from the kit still looks perfect - although I tried two others since fitting that one just to be sure.

I'm going to shoot the air out of the gun this weekend just to get some enjoyment out of all that hand pumping, then try to figure this out.
 
I'm at it again with another bsa ....so far its holding and it came Filled at 3000

I put about 60 rounds through mine today ,and Mike I agree, it is really nice. I only own low end pellet guns RWS Diana 34 and a crappy Gamo 177, don't even remember the name, both spring guns and the BSA is a different animal. Shooting in the backyard at 25 yards and I am not an experienced air gunner like most here, but I was grouping 3/4" at 25yards first time out. I'm sure that will improve. My son put 10 shots in the same ragged hole, must have been almost 1/2" and he's shot less than I have (but has better eyes!) so I think the gun would be very accurate in experienced hands.

My two stacked o-rings are still performing, I filled the gun again after the shooting session to about 200 bar and will check it tomorrow to ensure it hasn't leaked down but so far so good. I think I am going to lave the double stacked o-rings alone for now. They are working so why prolong my agony by screwing with it?



Only funny thing is that the gun at 25 yards is destroying my diy pellet trap. I sloped the back of the trap at 45 degrees and used two layers of ptfe cutting board on top of 3/4" plywood and the cutting boards are getting beat to death! These ain't your fathers air rifles!
 
The R10 is a very good shooter. I have taken birds out at 100 yds with mine. rwsmike glad to see the new one is working out for you. The aluminum wheel magazines are the old style and were fased out of production about 1 year or so ago. I do like the plastic wheel mags better because they shifted the position of the oring so it holds the pellets a little deeper into the mag. With my .177 aluminum wheel mags my pellet skirts would occasionally hang out and get jammed causing a flyer. The plastic wheel mag holds the pellet deep enough the skirt never hangs out. My .22 cal aluminum mags work fine as do the plastic wheel mags in .22.
 
Benjamin Marauder mags sell for $12 on Amazon Prime. They are essentially the same to manufacture as the BSA mags. Sure would be nice to get some spare R10 mags without the credit card catching on fire.

Ken - In no time at all you will be shooting your 25yd group at 50yds. Quick question for you. Is there a reason that you only fill to 200bar instead of 232bar?
 
Rodeo,

Ha Ha, so far just laziness! The Hill pump seems like a quality item but it's still quite a bit of work once you approach 200bar. so far I've just wanted something to test for leaks and 200 seemed like enough. I will start approaching the "250" mark on the rifle gauge next time out. 

Agree on the mags, I bought a second one with my original PA order and it stuck in the my throat a little. Still mags for a daystate are $100! 
 
I haven't done a shot string because I feel I need to put a few pellets through it to get the reg settled I just tk a few shots with roughly 2400 bar in it and the chrono said 896,899,895 jSB 18s...I feel that's spec because 14 grain would probably be 950. Its possibly shooting hot but God it's so dam accurate ....been a long time sense owning a rifle . I havnt owned a airgun over 38 inches in a long time plus I wanted this gun for one reason and that's benchresting.
