Goodness, you know how much shooting it takes to wear a muzzleload barrel? Alot. It ain't like a 300RUM or 223WSSM. I observe wear carefully with a hawkeye borescope. Ask one shot on here. some of those savage guys push JB's thru 2000 strokes! The only think I ruined a barrel with is firelapping in a centerfire. Rounded off the rifling cleanly. Quite disappointing.

Also, isn't butches an ammonia base solvent? Won't have much effect on plastic fouling will it? Just curious cause of the windex idea people do. I don't, just wondering ammonia is good for powder to instead of copper.
