The .452, 300 grain XTP is ALL that I use. Never had a deer go farther than 20 yards. Always good blood, most drop on the spot. The Hornady sabot is a little tighter than the T/C version. I was very disappointed with the SST's performance, no blood, no expansion (even thru both shoulders). The XTP or Gold Dots would be your best bets. My best 3 shot group at 100 yards was a little over 3/4 inch.
