Anybody know where I can get published load data for BP in metallic cartridges like 45-70 and 44-40?
Got a Rifle Model 1873 trapdoor I want to shoot. It's in marvelous shape, bright bore and chamber, coupla busted minor parts like rear sight leaf spring and stacking swivel.
I know the "70" is originally 70 grs of FFG black powder, but what about pyrodex substitutes? I also hear that it's hard to get 70 grns into modern cases due to the thicker case head design.
Thanks a bunch!
