There are ten guys in our hunting club. Other than me and my brother-in-law, none of them are muzzle loading enthusiasts. The others are "once a year/extend the hunting season" kind of guys who shoot sabots exclusively.

I shoot mostly round balls and sabots for hunting, but play around with big lead on the range. I used to hunt with a TC New Englander and 410 grain Great Plains bullets. But sold that gun a few years back. My b-i-l used to hunt with his TC Grayhawk and 385 grain Great Plains bullets. But for the last few years his Grayhawk has sat in the cabinet while he hunts with sabots in his Knight or TC Omega.
