To clean, break the action open, remove extractor, remove plug with proper socket wrench. Clean from breech. Cleaning between shots depends on what kind of powder your using. I use Blackhorn 209, no cleaning needed till end of shooting. Triple 777 will need usually between shots, other bp substitutes vary, depends how hard it is to load. When cleaning between shots, clean from muzzle. Make sure your seating that sabot and bullet against powder every time. Use a good anti- seize compond when replacing your plug. Bore Butter is a joke stay away from it. My advice get an experienced ML shooter to coach you at first or do some serious study, your basically creating a caseless handload with every shot. Enjoy but understand what your doing.
