Thread: KG 12 copper remover

Pretty sure there was some quite convincing field tests on KG12 and others. Duley mag? Chucked a Barnes bullet in the test fluids and measured weights before and after. The KG12 bullet was the only one that showed significant weight loss. I like the stuff. Mine comes out black/blue at start with KG12. Some carbon removers do take a lot of copper out. IMO people often overlook carbon fouling. I think in some rifles its worse than Cu. If all the carbon is not gone you may not be able to attack the Cu. Or, you may just have a great barrel for not fouling.
