I have a new Shilen Match Select barrel chambered in 223 AI . I did a barrel brake in procedure and noticed at that time that I was not getting any copper fouling. I use M-pro 7 and Sweets to clean my guns. The barrel now has 105 rounds through it in total. My last range season was 40 rounds and when I cleaned the barrel there was no sign of copper on my patches at all. Is this a good thing or a bad thing? As far as accuracy goes the best I have been able to do is a little under an inch at 100 yards. ( this might be due to the fact that I have been fireforming 223AI from regular 223 brass. I have never had a barrel that didn't copper foul at all and was just wondering.
