Found an old remington #6 at the local flea market this spring and decided it needed a home.
Rusted bore, no rifling to speak of, so..
I took a leap and ordered a piloted bit and a chamber reamer from Brownell's, and a liner from Dixie Gun works.
I'm no machinist, but it seems to shoot.
Today I got a few groundhogs with it, and had to wonder how many kids over the years did the same with it.
