Been pondering a 380 acp bolt action rifle .... savage 325 action .... used to be a 222 remmy.... the bolt face is close....could in a pinch make 380 brass from 9mm or maybe even 223/556..... 20,000 psi operating pressure .... 80-100 grain boolits .... quiet compared to a 9mm round... a 16 inch barrel would smack small critters ..... just thinking out load .... any thoughts appreciated ..... regards
