FWIW, in “breaking in” my new ARC barrel I did as wrote above. Shot 1 clean. No copper. Shot 3 clean. No copper. Shot 5 clean. No copper. At that point I was happy. Last session I shot 20, shot count now 60+, and cleaned for the heck of it. I couldn’t find a spec of copper. I am going to shoot it today to fowl the bore before tomorrow’s shoot. Will be interesting to see if there is a ccb shift with a barrel this smooth.
