Has anyone ever used a tornado brush to clean there revolvers bores and or there cylinders. I have used them to clean my shotgun choke tubes but never a rifle or pistol bore. Can anyone give me advise as to not use them or if there ok to use. They look to be aggressive but they do clean a stainless steel choke tube out with out any scratching. I just don't want to take a chance on a barrel until I get some responses from others.
