I just bought a Navy Arms 45-70 Rolling Block from Gunbroker and it's here. It has a heavy round 1-20 twist Shilen bbl. I have been loading and shooting for over 20yrs but I know nothing about the rollers or BPCR for that matter. I just dig it for some reason and want to learn how to do it right.
I have seen things written about #1, #2 and #3 actions but I don't know what the difference is between them. Also, I don't know which one this is.
I bought a cheap Lee 405gr mold to start out with but any advice would be highly appreciated.
Thank, Tom
