A friend and I went and shot the .62 smooth bores today, usually use 2f goex, friend brought some 1f goex to try.I shot better using the 1f today than I shoot the 2f, noticeable difference. He shot a 10x and 1 touching the 10 ring at 50 yards offhand, we come to the conclusion that there seems to be a big difference in accuracy and recoil. Might have to try some more. flinch
