9mm EDgun Leshiy 2's

Not sure of exact round count from my .25. I need to shoot it thru the chrony to find out when it falls of the reg. But a close estimate is 40 shots. The 25.39 grain JSB’s are moving an average of 1,031 fps. I would slow it down some but it’s inside a squirrel head at 50 yards. The 34 grainers are moving in the 900 fps range. Can’t remember exact. Brian said it would shoot the 34’s better so I’m sure he had it set for them. But the 25.39 are more accurate.
Has anyone cranked it up to 350 bar, I would think much better shot count. Also, what kind of accuracy are you guys getting with 22 & 25 cal slugs at distance. Gun sounds too good to be true; one barrel 4 calibers!
