Ok, Im in NC and I dont know exactly what the rules are on "Muzzle Loaders". My dad has some pretty fancy black powder guns like old Maynards and some rolling block style rifles. Regardles, these types of guns take pre loaded cartriges (bullets and brass casing loaded with black powder) and they fire with caps and hammer. What Im wondering is if they really need to be "Muzzle Loaders" or if you can use these cartridge style rifles.
