I have been using the Hornady SST 130gr for two years now. They are accurate and very deadly. However, once again, like the Nosler BT's if you shoot them into a lot of meaty flesh - hams, loins, shoulders, you will have meat damage. Strive for the behind the shoulder shot and they perform superbly.
Before anyone gets riled, I know any bullet will destroy meat. I have never shot a deer in the ham with any bullet with my 270 where there was not a lot of meat damage! The SST performs as well as any other plastic tipped bullet in my opinion. It fragments a lot when it hits a solid mass, like many of the lighter bullets do. But, overall they are very good and that is what I am shooting.
