I have used the 250 gr. Barnes with very good results. They create a big wound channel and really dump animals hard. They also seat very hard in my T/C guns. I would recommend changing sabots to the Harvester with this bullet.

Have also used the 250 gr. Shockwave, which is the same bullet as SST with a slightlyeasier seatingsabot. These have also been very good - great balance of penetration and expansion. And they fly very well at long range. Maybe see which ones shoot the best on your rifle.
