rabbits with sling shot and rocks, why BOTHER with 1 MOA, bull barreled 1022, hmm?
It's either one or the other. You either "need" more accuracy than a canned M21 Beretta .22 pocket auto offers (8" OAL, 14 ozs, can and all) or such a M21 has PLENTY of foraging potential. Since it will take rabbits to 30m, Weaver, and 45m, braced firing position, it easily has 10x the effective range of slingshot and rocks. So you are fos about "needing" accurate .22 rifle, or you are fos about the slingshot and rocks. which IS it, hmm?
