This is a terrible story... I bought an old percussion muzzle loader in 1962. It's a half stocked gun in 50 caliber. In those days it was hard to get proper bullets so I shot 45 balls with a thick patch. The rifle shot like a dream, but my mother'd scream about the smell when I cleaned the gun...even if I did it outside. I was 16 at the time. So one day I didn't clean it, and didn't get to it for about six months....great, right?! The bore which was bright and shiny is no longer. I've heard that old bores can be "freshened". Does anyone out there know of a gunsmith who can clean up my old guns bore? Thanks for the help.
