Hornady SST 7mm .284 154gr Polymer-Tip Hunting Bullets
The Hornady SST (Super Shock Tip) in 7mm .284 at 154 grains is a polymer-tipped, boat-tail hunting bullet designed for rapid, reliable expansion on impact. The hard polymer tip acts as a wedge on contact, driving into the lead core to initiate fast expansion, while the InterLock ring mechanically locks the core and jacket together to maintain bullet integrity and maximise weight retention for pass-through penetration.
The secant ogive boat-tail profile reduces drag and improves stability, providing a flat trajectory ideal for open-ground stalking where shots may extend to longer distances. A mid-body cannelure provides a secure crimp point during loading and works in conjunction with the InterLock ring to prevent core-jacket separation.

Used these bullets in a 7mm .284 rifle for deer hunting. The expansion was consistent and reliable. The bullet performed well at 300 yards with good penetration and minimal fragmentation. Easy to load with the cannelure providing a solid crimp.
Edward Campbell –
Good performance in field conditions. The polymer tip expanded quickly on impact, which is ideal for quick, clean kills. The weight retention was excellent, even at longer ranges. Slightly more expensive than standard bullets, but worth it for hunting.
Frank Rees –
Felt a noticeable improvement in shot consistency compared to older bullet types. The InterLock ring kept the core from separating during impact. Works well in both open fields and dense cover.
