Has anyone tried the KG 12 solution to remove copper fouling? I read an article that claims it is the best for that problem just wondered if it was before I ordered it.

Awsome stuff, The bad thing is without a borescope you can't tell when all the copper has been removed. Most copper cleaners use amonia, when amonia reacts with copper it turns blue. When using an amonia based cleaner you simply run patches through until there isn't any blue color left. KG isn't amonia based so the patches come out nice and clean all the time, I've cleaned several barrels and looked inside them after following the directions and there usually isn't any copper left. There will be instances it will not clean it out 100%. You'll see that happen on a barrel that has been neglected or on a real rough factory barrel. Be sure you have the carbon cleaned out before hitting it with KG12. KG12 doesn't attack carbon fouling.
