It took the accuracy level down from 1/2" gun to about an inch. Matter of fact, I don't remember anything about the fouling on the gun. I like a gun that will shoot at least 1/2" groups. But, the barrel did look rather rough inside, thus the increase in group size or so I think.

I did not mess with it any more to check fouling, I just had it rebarreled to a 20 TAC.
