I'm curious about all the calibers with alternate ammo possibilities like shooting 38 spc through my 357. Will any other like 38 Super or 38 Long Colt work? I know with 32 H&R mag you can use 32 S&W Long, any others? I've heard 45 Long Colt in a .410, sounds iffy to me. Anybody an expert on compatibilities? Good stuff to know post SHTF for scrounging.
