I have been judiciously reading up and deciding what I need to gather up to try my hand at PP for my 45-70bpcr Pedersoli Sharps Buffalo. Specs are 32" 1:18 and a .458 bore. Intended use is 100-200 steel ringing, mostly, and when I get to 600 precision target work. I may try my hand at some BP silhouette one day also. Powder is OE 1.5. So thinking I should get a heavy, 500+, .443 wrapped with a paper that with 2 wraps gives me +.025. Does that sound right?
