[QUOTE="Archery1973, post: 732819, member: 41463"] I don't clean for copper after barrel break in. Once broken in, I only use M Pro 7. Kelly McMillan told me to never clean for copper unless it is excessive. Todd Hodnett has said he never cleans for copper either. He took a 1/4 MOA gun and cleaned all the copper fouling. It turned into a 2 1/2 MOA gun. 45 shots later.....it settled back into a 1/4 MOA gun with no copper cleaning. It's in the Magpul video. [/QUOTE]
