Has anyone tried using 45-70 boolits sized down and stuffed into a 45 cal muzzle loader? I see Lee has quite the selection. The 459-405-HB is a nice hollow base boolit that I think might work well. They also have the big momma 459-500-3R which looks very interesting if not scary.
My intention is to buy a CVA inline for these boolits but I want access to cheap boolit moulds first.
I will be buying their improved mini but that only tops out around 294gr.
