Extremely minor. I just finished working for two days on a 300 WSM that hadn't had the copper removed in 500 rounds. It still looks worse than that, but I'm calling it good. I figure I'd have to work for two more days to get it all out.
FWIW, very few rifles will shoot their best without a certain amount of fouling.
