Let me run a thought by you and see if I have my right mind set. I have been wanting to shoot BP in my .45-70 B-78 for a while and was just waiting to get another roundtuit. My thinking is to load a primer charge of 5-8 grains of Unique, 4759, or 4227 to limit the amount of fouling left in the bore. I don't want to use a blow tube or wiping rod after each shot, nor to have to use a card wad. Will a g/c boolit take the place of using a card? Will I still need to compress the B/P and will it be permissible to use 3F instead of 2F? Standard or magnum primers? -JDL
