before season I loaded about 125 rounds of the hornaday 150 grain SST's. Loved the grouping but when I took them to the woods that was another story. Opening day shot a 8 point and the bullet did a complete thur and did not expand. Didn't think to much about it at first, but after hitting 5 does and knocking them down, and they would get up and run off without one drop of blood, I switched back to my seria bullets.
Saw a 200 grain MZ Hornaday SST bullet that was pulled from a deer and it was still intact and never expanded.
So I can say I don't like them.
