The 154 SST works extremely well on pretty much anything out of the 7. I've taken groundhogs, pronghorn, whitetail, mulies, a couple of caribou, red stags, elk.. oh and I shot a red squirrel with one once too! Interestingly, while the SST will shoot 5/8" all day long out of my gun the 154 Interbond will not. I've never been a fan of "premium" bullets anyway because I'm a true believer in the only thing premium is the price. I make this comment in the context that the "non premium" bullets work great and in a lot of cases much better when the game is smaller and the impact velocity isn't as high so I've had no need to pay more money for the same or worse results.
Antelope at 409 yds and stag at 190 yds...both are obviously dead
