I was just wondering if anyone had a custom barrel that still had bad copper fouling after they broke it in? My first .308 Krieger stopped showing copper after the first three shots during break in. Now no matter how much I shoot the .308, all I get is powder fouling. My 6.5x47 with a Bartlein is on the 8th round from break in and is still showing some copper after cleaning every round. I’m not worried yet, just wondering what other people’s experiences where?
