And it was also fun once, playing with a Colt Walker replica. I found that the first cylinder full of shot would usually go into 2-3" at 25 yards. Let's just say I was stuffing A LOT of black powder into it.
The gun leaded badly enough at those velocities that accuracy was dramatically impaired on the 2nd cylinder full of shots
Pity I didn't have a chrono in those days
Impractical in its size, it would still just pretty much hang out there, easy to shoot well. I foolishly gave to to my brother one year - he was so mortified by the thought of a chain fire that he sold it.
