I have used the Hornady 150 gr. SST's in my 270 WSM and so far have gotten good accuracy, 1.25" @100yds. It was my first load for the 270 WSM so I might even be able to shrink this down a bit. I have not gotten to use them on game, however they will go thru about 4" of a poppel tree and then about 2" into another poppel tree. I have used the ballistic tips in my 300 WSM and 7mm-08 and they seem to be very similar to the SST's. I think any of those, and the swift scirocco for that matter, will be a great bullet for you.
