Take just along if not longer to load, have to remove cylinder and use special rig to load. Not that easy to clean, if you use Triple 7 in a black powder gun you can clean it with hot water not chemicals and you don't need another certificate to use it. I didn't see any great improvement in accuracy with it.
I think the most telling is I've seen it once at the range while his other muzzle loading pistols I see all the time.
These are also good points!
