One of my best shooters needed to be re-broken in. (Actually, I doubt if it had even been broken in, in the first place) A CZ550 in .308, with a 26" barrel I picked up had some serious copper fouling. No matter how much I cleaned it, the patches would always come out with blue.
I finally hit it with some Tetra for 2 -3 cycles.Got the copper completely out, and did a semi-formal break in. Groups definitely improved, but the barrel still fouls - just not quite as severely as before.
