ditto to everyone else. Anytime I've hit a deer with a M/L sabot it never opens up. I've shot deer with SST sabots from M/L's and shotguns and many times ive watched the impact, watched the deer run and collapse, but when i go to the impact point, theres little or no blood until i get right up to the animal. yeah the SST's are accurate, but they don't open up worth a damn
