Either one would be perfect for deer hunting. I've killed a large pile of deer with SST's in my 7mm-08 with no problems. They are a tad soft so they may not exit, but they do turn the heart and lungs into a liquid pulp. That said, I reloaded some 150 grain Speer BTSP's for my .30-06 and I killed a deer with one of them with no problems. I got really good accuracy with them and a really nice exit hole to boot. I'd probrably choose the Speer bullet if I had them just because they will probrably exit most of the time. But either one will work fine on a deer.
