So you think your gun had alot of copper in. I cleaned the copper out of a gun for a friend that was 30 years old and had a few 100 rounds a year put dowm the tube and had never seen any copper soulven. After 50 patches of Sweets, and the last as blue as the first, I went out and shot it. He had quite shooting it because it was no longer accurate enough to hit a groundhog at 100 yrds, and I put 5 rounds in at abt .600 so I quit cleaning the bore and cleaned up the rst of the gun and sent it home. He used it for another 15 years untill he died and that was the only copper solvent it ever saw, and it was still shooting good.
