Depends on your bore, of course. I found the super glide sabot to load easy. Not NEAR as easy as a powerbelt. Not sure what load or gun you are using, but I found XTP'S to perform better on deer at muzzleloader velocities, with little practical penalty to bullet drop. Within 150 yards, there is not a whole lot of difference. I shoot 240, 250, and 300gr. XTP'S over 100gr (loose) T7, out of a 29" 1:48, 50cal.
