RE: rebore a pitted .54 Renegade to 20ga
Seems any good gun smith could do it if he has the right equiptment....I think it would
have to be bored out and i'm not talking with a drill bit..They would likely have to use
a boreing bar...And you would probably be the one buying it as he would have no use
for it again..I know when I had a 38-55 bored out I foot the bill for borer and liner...
I would look around for another barrel if possible....Just my 2 cents worth..
