Found a .58 finally. She needed some love to put back in firing condition, so dirt cheap . Its a Navy Arms Hawken Hunter .58 cal, full 1 1/16 barrel patent chamber bored. Had half a minnie ball stuck deep took me some work to get that out then a good cleaning and anipple swap. BOOM its a great shooter, really heavy and a lot of fun. Ive run it as hot as 150grn 2f behind a 611grn Maxiball OH MY WORD thats strong. But with just a patch round ball and 90 grn 2f its a pure joy and accurate to 100yds so far about my max for irons anyway. Theres a pic of a cute lil 50cal bullet next to a 600grn .58.
