I have the Mossberg muzzle loader barrel. I shoot pure lead lubed with my own recipe, hollow point and hollow base 385 grain bullets with loose 777 ffg powder. It works great. The only drawback is cleaning the receiver and action after shooting (I normally do this anyway when I use the shotgun for waterfowl if it gets wet, so I am pretty quick at putting it back together). It does require disassembly of the action parts (not trigger group) to clean really well. The barrel is a snap to clean. Remove and clean with hot soapy water and a bore mop. The breech plug does not come out, but is still easy to clean.
