I had finally gotten around to "testing" my mousegun 32acp ammo. Fio 61g really surprised me. In wet-pak, phone books, it actually penetrated further than 9mm fmj? About the same, but further? A lot of the other brands didn't expand consistently(1 exp 2 didn't). I never really considered the 32acp, but wasn't expecting this. I knew not to underestimate 22lr, but now the 32acp also?
