I used it down the bore of an inline so far. From what the guy told me a law enforcement officer told him about the product and they use to clean there handguns. I story I was told that when these officers go to the range they shoot 100 to 200 rounds and when they clean them there is not near as much power residue when they use the stuff. I guess the guy that came up with it was a the military. I am hoping to hear other people input on this stuff.
