I have a RCBS 577 Minie ball mould with the hollow base plug for my 3 band Snider. Is that the same bullet as for the Springfield rifle-musket? I also had a repro Parker Hale Musketoon 1863, but that was a brutal pig to shoot with the 577 minie bullets. I was going to have the barrel sleeved to 450, but someone coveted it so I sold it.
I had a Parker Hale 2 band 577 Enfield replica, I should have kept that one, 5 groove rifling and alol. How many grooves did the 58 Springfield have?
