Hammer49,
Before you go swapping out sabots, try the Hornady SST of choice with the supplied sabots 1st. If you get good accuracy and the sabot is not too loose nor too tight going down your barrel, then your done except for dialing in your sights. If the regular sabots are too tight, then try the SSTs packaged with the "LOW DRAG" sabots. The latter worked really well for me in my tight barreled CA Wolf.
Good luck and have fun.
