Many poor famliys only had one rifle 100 years ago,,,
A 44-40 ,32-40, or a 32-20 were comon choises...So I think a .357, 30-30 or 44 might work.. And a 12 shotgun barrel...
Is it cheating to say first choice would be a 308 with a adaptor to shoot 32 acp?
If the reason was, no $ I could shoot cast bullets -- or get Mil. surplus. Dan
