I started using tetra gun bore conditioner on it. When I first got the barrel had so much copper fowling in it within a few shots that it would go nuts. I read a post on a benchrest forum where a gent was having problems very similar to mine. He cleaned the bore with CR-10 them used a bore snake coated with tetra gun. Usualy about 3 strokes with the snake. A couple of shots to burn the excess tetra then about 20 shots followed by the bore snake. After a while the copper quick sticking. I had a thread on here about the hole thing if it is still here I will pull up a link.

Maybe he doesn't have a borescope...
Nope if I need one of my gunsmith buddies will deal with it.
