Yes, M-Pro 7 gun cleaner will clean any firearm that uses black powder.
The best way to clean a black powder gun is to first remove any unburnt powder by dry brushing the bore. Then spray a liberal amount of M-Pro 7 gun cleaner down the bore and let it soak for 10 minutes. Now you can run some clean patches down the bore. Done. You won’t need to use a bore brush.
