Thanks! That's actually the .54 cal 1863 'paper cutter' version. A fun gun to shoot. Has more felt recoil than my .416 Rigby Ruger 1. I make up the paper cartridges with the Sharps 'Xmas tree' bullets. I'd say it was my favorite....but then, they're all my favorite! I have yet to try any of the Billy Dixon long shots with it. Bill
