Bore butter has its followers. Some guys swear by it and others don't use it at all. Cayugad doesn't and I'm always picking his brain for info or at least reading his recommendations. I personnaly use it and have had good success with it. Of course I only have sidelocks and all my cleaning is done with hot soap and water, hot water rinse and bore butter. I just have an adversion to mixing any petroleum based products with black powder. I suggest you follow the manufacturer's recommendations for cleaning.
