As may have been said. After a decent round count, the copper may fill in some imperfections of the C.L. So clean the paste that comes with before shooting. Then shoot it and check accuracy after 200 rounds. Then if you ever see accuracy totally take a crap, clean it.

Sometimes you can run some nasty ammo that the barrel may not agree with and it could bite you. In the end, shoot it and have fun.
