If you can keep those SST's under MOA at all ranges you plan to hunt I'd say you've found your hunting load. The SST's have 2 "interlock" rings between the jacket and the core (if you include the ring caused by the cannelure).
My bullet of choice for hunting with a 308 is the 165gr Barnes TSX since I want one load for both deer and elk and it hits "close enough" at all ranges verses my 168gr BTHP loads that I don't have to change ballistics in my head. I bought a box of them years ago, and eventually ended up loading them for friends who did a lot more hunting than I did, I actually still have some of my original batch left (I shoot a lot more than I hunt).
Good luck hunting.
Machine guns are awesome until you have to carry one.
