The .25’s go over easily. I stripped and polished my striker, added a small piston weight and when I put it back together it was shooting a lot nicer. Shot cycle was better as well. Put it over the chrono and.........oops, back on the bench. It’s running at about 11.8 now with marksman but it shot nicer before. Shame really, but that’s how it goes. It’s still much improved from as it was standard before it was tuned and polished. I think they’re designed to run at about twenty, and they’re detuned to run below twelve.
