45-70 loads
In discussing loads,we hav'nt touched bullet dia or alloy.These issues don't mean much with a ruger using jacketed bullets,but is important in antiques.
I only have two molds,a Lyman fn 405 gr,and an old Ideal 417gr 457 dia w two grease grooves in spitzer form;[for it's day].I have to use soft enough lead to bump up in trapdoor. BHP has some Hollow base molds and I'm sure we can get Him to post some info when He checks in.
For the record,I use Lyman 405's as cast from wheel weights in Browning 1886,w 28 gr 4759,or if I want to damage tissue[mine],I use 50 gr 30-31.
