Penetration of .380 ACP.

Plot device question - could you stop a .380 ACP round with a briefcase full of tightly wadded money? You can assume FMJ and a medium power cartridge.

Probably, but don’t try it. :slight_smile:

I have shot phone books with my Makarov, which is chambered for the sorta-similiar 9x18 round, and the phone book handily stopped both HP and JHP rounds.

Err, JHP and FMJ, not HP and JHP. :smack:
