In short range benchrest, the reality is that with ten, five shot matches a day, plus sighters, and typically two days of shooting, cleaning during the day, at the range, with limited time, is pretty much a given. I have always used bronze brushes for these situations, and unlike a lot of fellows that speculate, I have looked at the interiors of all my barrels, many times, with a borescope. There was no evidence of scratching from brushing. I am a lot more concerned about careless, and excessive use of even the mildest abrasive than anything that a properly used bronze brush might do. If you don't shoot much, and you have all the time in the world to clean, there are a variety of approaches that can work, but I can tell you for sure that I know of more than one instance where someone read something in a magazine about not using brushes, and eventually found that he had a buildup that was hurting the accuracy of his barrel, Of course these fellows shoot a lot. I have used Wipeout, on varmint barrels that were cleaned at the end of the day, but even with these, a friend,who owns a bore scope found that he was starting to see some carbon accumulation happening over the course of several cleanings. The good news was that although taking our the Wipeout with patches did not remove everything, evidently what was left behind was made less stubborn, so that a few strokes with a bronze brush and some Butch's took care of the problem. Proper barrel care takes experience, and varies with the barrel, velocity, bullet length, rifling twist, pressure, jacket material, and what powder is used. It should be remembered that hard carbon and powder fouling have two very different cleaning requirements. Often in online discussions, this is a distinction that gets lost or ignored.
