Just get the right thickness of sabot and the correct diameter to match the bullet your going to use, for the gun you shoot. For instance, I tried to load a Hornady SST in my Black Diamond XR and it was so tight, I broke my short starter. Yet I load their Shockwave (same bullet different sabot) with no problems and excellent accuracy.
Many rifles do require swabbing the bore between shots when shooting sabots, so keep that in mind.
