New to me 15in Evol in .22… needed some work from the beginning and I though I got it there but this last thing is damn persistent…
It’ll shot a handful of shots or so at the speed I set it to (965fps with 18grain / 890ish with 22 grain), then 1 to 3 or so shots way slower, then back to set speed. Example:
This happens with any and all pellets I put through, 18gr, 22gr, 25gr doesn’t matter. With the 22 it’ll shoot 890, then 830-850, then 880 again. 25gr 840ish, then 800 and back up.
Spread was way worse when I got it. What I’ve done so far is: Set reg to 2,100psi, pulled hammer and spring, cleaned hammer channel properly, cleaned and polished hammer and spring, balanced hammer to reg at around 96.5-97% of max speed…
I’m almost guessing the reg is shot but, per gauge, holding pressure constant. Interestingly, it has the purple reg but based on the rest of the gun and serial it is a newer model and should have the blue reg, right?! The gun also sounds different when the slow shots occur, I can tell without looking at the chrony numbers… obviously also from POI… when it’s shooting as it’s supposed to it’s very accurate with the 18gr but the weird slow shots are all over so can’t trust it for now. Tried with different mods obviously but no change. The one on it right now is a Falx, which can go up to .30 so there shouldn’t be clipping.
Hoping the Evol fanbase has ideas
Thanks in advance!! Orings to rebuild the reg and basically the entire thing are on the way.
