Just acquired a new (70's vintage) 50-90 Sharps. I've been a shooter/handloader for some 40 years but all modern revolver and rifle calibers. Also did some muzzle-loading and cap and ball, but this 1800's cartridge stuff is new to me.
I'm looking to talk over some things like slugging the bore, what bullet weight and smokeless loads and such. Thought maybe starting with Trail Boss.
