Pro-Shot Copper Bore Cleaning Solvent IV is made specifically for copper and powder fouling, while preventing rust in your barrel. This formula uses positively charged ion additives that have a special affinity for copper and its oxides. These ions search out and release the copper from the surface of the bore to provide a superior clean surface without copper and powder fouling.
