I have custom built 50 underhammer I picked up on another site heavy barrel not sure the twist rate seems to shoot round balls pretty good haven't had time to shoot it much, I bought a TC maxi hunter mold to try in it but I haven't shot it enough to tell, I just thought it was a interesting rifle and thought I'd share.
The target bottom left was round balls the right the maxi hunters shot at 25 yards. No real load development yet.
