Following the advice of Unclenick and the article he attached to his note, I got some of the water based (surfactant type) copper remover. I mentioned that earlier. Well today I got serious with it on two rifles that I thought were mostly free of copper. I was way wrong. The 220 Swift and my Sako 270 dribbled an awful lot of blue from the ends of their barrels, and it wasn't a light blue either. It was a dark blue. I was very surprised, since I would've told you yesterday that they were both clean as a whistle. I don't think I even got all of the copper, but will wait for that Boretech Eliminator and go at it again. Who'd a thunk it?
