Rifle Bullets 270 Caliber (.277) 130 Grain Boattail Super Shock Tipped Packed Per 100 Hunting for a bullet that will give you enhanced velocity, controlled expansion and pinpoint accuracy shot after shot Well, Hornady has a tip for you. Pick up a box of SST (Super Shock Tipped) bullets - the next step in the evolution of the hunting bullet. How does the SST reach this higher level of performance It all starts with a premium-polymer tip that begins working the instant you pull the trigger. The sharp tip and the bullet's profile combine to improve the SST's ballistic coefficient. The result is greater velocity, pin-point accuracy and more downrange power - all real confidence boosters on those tough, long-range shots. But the tip's job doesn't end there. In fact, it's only just begun. On impact, the tip is pushed backward into the lead core to initiate immediate expansion. The specially designed jacket grips and controls the expanding core, allowing the bullet to reach its optimum diameter while retaining mass and momentum. This chain of events creates deep, dramatic wounds the instant the SST penetrates the hide. The SST's InterLock ring ensures perfect expansion and higher weight retention. The jacket's thickness is precisely controlled to ensure optimum expansion. The cannelure gives you precise crimping during reloading, and grips the core in the initial stages of expansion. Every part of the SST, top to bottom, inside and out, is designed to shoot flatter, fly straighter and hit harder. Note: These are component bullets, not loaded ammunition.
