Don't reverse the brush, don't use a bronze brush only nylon, unscrew the brush, break in and clean every round for the first 10 then clean every other round till you have shot 50 rounds, don't use JB, don't use Isso, use toilet bowl cleaner to clean your rifle, shoot till accuracy falls off, then clean . (Accuracy fell off right in the middle of a match). All of this learned from the internet, from people that don't give their name. I think i am going to listen to Bart in his interview with Erik. Barthas won a few things and I think i can trust him.
