Short for "Super Shock Tip" the Hornady® SST® is designed to deliver tremendous shock on impact while expanding quickly and reliably, particularly at higher velocities. Flat shooting and deadly accurate, it's an ideal bullet for whitetails, as well as most North American game animals from antelope to moose and similar-sized African plains game. The SST® creates a devastatingly large wound channel. Features: Polymer Tip The sleek polymer tip increases the ballistic coefficient, making it more efficient. Upon impact, the tip also initiates controlled expansion. Secant Ogive, Boattail Profile It’s a fact: bullets that travel faster hit harder. The Hornady® secant ogive gives hunters the speed, ballistic efficiency and downrange energy they’re looking for. Cannelure Provides accurate and consistent crimping, and also works with the InterLock® ring to control expansion. Interlock® Ring Ensures the core and jacket remain locked solid during expansion, so the SST® retains the mass and energy needed for dramatic wound channels.
