Lonewolf. I always wanted one but seems like such a hassle shooting 5 or six shots then going thru that tedious loading process. I would be nice if you had a half dozen extra cylinders so you could load them all up at home then just cap them at the range. And then, like you said, the cleaning. Sounds like it too would be a hassle.
Also, reading your post - did you not put anything over the ball? If so, that could be a dangerous situation. Isn't the reason for the top wad or grease so as to seal the cylinders so you don't get a spark into the adjacent cylinder possibly setting it off.
