Cleaning isn't the bugaboo everybody says it is unless you shoot Pyrodex. I don't know a worse black powder sub. The fouling is abrasive and highly corrosive and must be squeaky clean within hours of shooting and then you'll still have to clean it again in a week or so.
Not so much with real black powder. I clean my competition muskets with nothing more than Windex. Windex contains water and ammonia. Water dissolves black powder fouling and ammonia neutralizes the acid. First the breech scraper, then a few shots Windex down the barrel till it runs out the nipple then patch till clean. Take out nipple and clean it and flash channel area with Windex. Lightly lube nipple threads and reinstall. Wipe down bore and outside with Marvel Mystery Oil and done. Entire process takes less time than to clean an AR15.
Other information for anyone considering coming over to the dark side, there is a parallel organization to the NRA for black powder and muzzleloaders, the National Muzzleloading Rifle Association. It encompasses nearly anything muzzleloading and black powder. The NMLRA started in the 1930s and was initially focused strictly on long rifles and roundball stuff. Fast forward and with membership dwindling and ground approaching, they opened up to more forms of black powder and muzzleloading. Now they have traditional round ball, Civil War arms, modern inlines, black powder cartridge, muzzleloading shotgun and more. They also are a very deep store of knowledge on real old school gun smithing and how the make all the stuff from back in the day. I can't recommend membership in the NMLRA for a black powder shooter enough.
The average modern shooter is too young to remember the heyday of muzzleloading in the 1970s. It was quite popular and guns were easily available. As time moved forward, many of those folks got older, died off or just quit. It just a factor of age, a person into shooting in the 70s was likely about 20 and that would make that person now 70+. Some stayed with it but many shooters migrated over to mainly modern arms. The problem there was a loss of knowledge and expertise in the black powder and muzzleloading fields. The NMLRA and those of us in black powder today are active in reintroducing black powder to the new generation of shooters (and that's partly why I work with Scouts and kids during summer camps). There's more to life than a "black rifle" namely Black Powder! It can be loads of fun and a great way to connect with history at the same time. How does that history benefit a new generation getting into black powder? Well, the old guns are often for sale a prices under the cost of a new one and usually much better made. If it's in good condition, a quality T/C can be had for about $400 or less. I've seen more than one in the past couple years sell for under that figure and be excellent shooters. In the world of Civil War live fire, there is no source deeper than the North South Skirmish Association. There's lots of Utoob reenactorisms, but if you really want to know how to make the old war horse do it's thing, come shoot with the N-SSA.
