Butch's New Black Powder Bore Shine was developed specifically for Black Powder Shooters who asked for a better, faster way to clean their rifles. Butch's Black Powder Bore Shine comes from a special cleaning solvent used by the U.S. Military. This New Black Powder bore cleaner, like the original Bore Shine, does it all. It removes powder, lead and plastic fouling faster than any other cleaner. Best of all it is odorless, non-toxic, non-flammable, biodegradable and protects against rust and corrosion.
