I have a couple of handguns that I seem to be having trouble with getting the copper out. One in particular is the G19. Even after judicious use of a wire brush and Hoppe's #9 or their Bench Rest #9 Copper Solvent solvent, you can still see the copper with a bore light running the length of the rifling. Is there better products than what I'm using for copper fouling? these are old standbys for years but don't seem to be cutting it anymore. __________________ Wanna kill these ads? We can help!
