John,
I have a friend in metallurgy. He has told me that you could take a bronze or brass brush and have several to do this test by the way. Mark and measure the piece of steel with a set of calipers on the mark before doing this. Now start scrubbing the marked area with brush after brush for 3 straight days if you like, and when you are done wearing out all those brushes, measure the same spot where the mark is, and you will get the same exact mesurement that you had before. He has told me that all a brush does to steel is polishes it. Now some will say you or scuffing the steel, but in reality all you are doing is polishing it. He ought to know. He's a very smart fella. He said no brass or bronze brush can in a metallurgical test remove steel from a rifle barrel. That's part of why I said a brush won't harm a rimfire barrel. This guy knows the facts about metals.
