I can vouch for the destructive power of the SST. Witnessed a shot from .308 just a week ago on a 4x3 Mulie at 100yds approximately. Near side shoulder destroyed, lungs converted to soup, bullet recovered rolled up just under the hide on the far side, retained 65% of original weight I believe. Deer went about 15 yards and finito! Pretty impressive at half the price of the Interbond. Far as I can tell the only real difference seems to be that the SST uses the cannelure to lock the core into the jacket where the Interbond actually has a special jacket with a thicker forward section that locks the core in. BC is identical, same polymer tip. I'd give the SST the nod. You may get a tiny bit more accuracy out of the Interbond, but if the shot is properly place the deer aint gonna know the difference between the 2.
