I have used the sst's in different calibers since they came out and I like them better than the BT,they are just as accurate for me and they do the job on deer.Have taken them from 20 to 200 yds and have yet to have one stop inside the deer,I guess mostly because I shoot behind the shoulder,It is the best bullet I have found for the muzzleloader also and they work on deer too.Wish hornady would come out with a 120 gr sst for the 7/08 and the 260.
