Hornady 8mm .323 170gr SST Component Bullets
The Hornady SST (Super Shock Tip) is a high-performance hunting bullet designed for rapid, controlled expansion and a large wound channel across a broad range of velocities. At 8mm (.323″ diameter) and 170 grains, it is ideal for handloaders building rounds for red deer, fallow, and similar medium to large game.
The hard polymer tip drives into the lead core on impact like a wedge, initiating fast expansion. The boattail base and secant ogive profile provide a sleek, aerodynamically efficient shape with a high ballistic coefficient. A mid-body cannelure helps retain the core and jacket during expansion, while the InterLock ring enhances mechanical bonding between the jacket and core for reliable weight retention.

Dylan Abraham –
Used this bullet in a handloaded round for fallow deer. The expansion was consistent and the shot hit hard with good penetration. The bullet performed well at medium range and the accuracy was solid. No issues with core separation during field tests.
Jacob Vance –
Felt like a reliable choice for medium game. The flat trajectory and controlled expansion made it easy to manage in the field. Slightly heavier than expected, but still within the intended performance range.
Rachel Metcalfe –
Excellent for handloading. The SST tip expanded predictably and maintained weight retention. Shot a red deer at 300 yards with clean results. Very satisfied with the performance and consistency.
