So Im guessing this has been asked before but since Im new to these kind of guns Im going to just ask.I just traded for an EMF sharps 45-70.Ive looked in several reloading manuals and I see about 3 different pressure levels.Some guys say you can shoot factory smokeless ammo in it and others say to only shoot black.Im guessing I should only load to not exceed 25000 cup but what about factory loads.Standard ammo?Leverevolution ammo?How high of a pressure can these things take and where is safe?....I have handloaded for years but I have never fooled with this sort of thing so any advice would be welcomed...Thanks Robin
