Yeah, I know it's verboden for N-SSA competition, but I shoot my original M.1863 three-band rifle casually. I dote on Hahn cardboard tubes, but seating a Rapine ringtail bullet leaves minimal room for powder. I'm happy with the 100 yard performance but can't help wondering: what would hotter 777 do? Anybody out there with 777 experience in a percussion Sharps?
