Regarding a previous thread, I have the same problem,(we all probably do). I've got some copper fouling in my bore of my 1911's. It's from normal use, only shoot FMJ or the occasional JHP. I clean my barrels after every use and they get clean, but there is some fouling in the rifling. Is that fouling going to hurt anything or start to get pitted over time. Or am I just worrying for nothing?
