Thanks. The rifle has some warts, but still should work into a good shooter. Green Mountain barrel, .45 caliber, 13/16 across the flats.
I lapped the barrel and put a slight choke into it. The muzzle is as machined, and the rest of the bore is relieved about .002 to .003. Followed the procedure in Ned Robert's The Muzzleloading Caplock Rifle Loads very easiley, those five shots had no swabbing between shots, and the fifth loaded as easiley as the first. I'm going to lap everything I build in the future that way, I am convinced that it helps.
