I bought some hoppes copper solvent yesterday on a whim and thought I would try it for my barnes solids out of my 7mm magnum. Does anybody use this and what do you think? I know original Hoppes #9 is very mild and I use it for my handguns and .22s but the hoppes copper solvent smells MUCH stronger but dont know how it will do on real copper fouling. I should also mention that I never fire more than 10-15 rounds between cleaning so fouling wont be severe.
