Now that is knuckleheaded advice, though Volquartsen does caution owners specifically not to use bronze brushes in its barrels, as doing so will void one's warranty. (At least that's what it said in the literature that came with my rifle.)Heard a store clerk tell a customer that he didn't want to use bronze brushes on his barrel as it would score and scratch up the steel and take out the grooves.
