BIG JAKE,
I went to Borders book store today, or as I call it, the library. They had a book on accurizing rifles, so I thought I'd take a look at their advise on barrel break in. Other than fire lapping, and hand lapping, they said to shoot and clean, recommend cleaning after every five shots for the first hundred. Their idea is that the bullets will break the barrel in if they can contact the barrel, without copper or lead fouling getting in the way. I have considered using a metal polish, and a tight patch to do the chamber area, and maybe the barrel, but I could never find a polish that seemed appropriate. So I'll just keep on shooting.
