IMO, the SST is the worst mistake Hornady ever made. They may shoot OK, but they are flimsy crap. An elk deserves better. I have never had issues with a standard Interlock, Nosler Partition, or Accubond.
It is your hunt, but an elk deserves better than an explosive piece of crap bullet. If you must use them, go with the 180-grain, as the other may very well fail. I think that they are actually worse than an A-max target bullet on game.
