Rem. 700

Catfish,
That is what I did. I gently tapped a wood dowel in the chamber to seal it and filled the barrel with shooter's choice copper out and let it work for about a week. Then I gave the barrel a good scrubbing with a bronze brush and kept repeating the scrubbing until the blue color came clean. It worked like a charm. It is about the best shooter I have now.
