Differences in bore finish dictate this more than any other reason. An older Shaw barrel needed copper cleaning after 20 rounds. A lapped Krieger I didn't do anything but patch after 300 rds. It sits at 446 currently with only a Wipe-Out cleaning after 200 rds +or-. Hardly any copper. Mostly carbon.
