Hornady SST 6.5mm 123 Grain InterLock Polymer Tip Spitzer Boat Tail Bullets (Box of 100)

Hornady SST 6.5mm 123 grain rifle bullets are engineered for reloaders who demand consistent, hard-hitting performance on medium to large game. The SST line combines proven expansion geometry with modern bullet construction to deliver reliable terminal performance across a wide velocity range. Whether you're working up loads for whitetail, elk, or other North American game, these polymer-tipped boat-tail bullets offer the accuracy and energy retention serious hunters rely on when it counts.

The polymer tip does double duty: it improves the ballistic coefficient for flatter trajectories and cleaner downrange energy, while also initiating controlled expansion upon impact. That tip works in concert with Hornady's InterLock ring—a mechanical lock between jacket and core that keeps the bullet together during expansion, preserving mass and creating substantial wound channels. The cannelure provides a consistent crimping groove and works alongside the InterLock to manage expansion rate, ensuring predictable performance shot to shot.

Built on a secant ogive boat-tail design, these bullets are optimized for velocity and efficiency. That means faster flight, less wind deflection, and more retained energy at distance—the ballistic advantages that separate hand-loaded precision loads from off-the-shelf ammunition. At 123 grains, this weight is a natural fit for 6.5mm cartridges like the Creedmoor and Grendel, offering hunters a bullet that balances recoil, velocity, and stopping power.

Each box contains 100 bullets, so you can develop your load and run enough rounds to confirm reliability before the season opens. For reloaders who want to match their ammunition to their rifle and hunting mission, Hornady SST bullets deliver the consistency and terminal performance that justify the effort.

Frequently Asked Questions

What 6.5mm cartridges are these bullets suitable for?

These 123-grain 6.5mm bullets are designed for cartridges in that caliber. Common applications include the 6.5 Creedmoor and 6.5 Grendel. Always verify compatibility with your specific reloading manual and rifle before loading.

How does the polymer tip affect ballistics?

The polymer tip increases the ballistic coefficient, which means the bullets maintain velocity and energy more effectively downrange. This translates to flatter trajectories and less wind drift at distance, while the tip also initiates expansion upon impact.

What's the InterLock ring and why does it matter?

The InterLock is a mechanical lock that bonds the bullet's jacket to its lead core. During expansion, this lock prevents the jacket and core from separating, keeping the bullet together and preserving mass. That mass retention creates larger, more consistent wound channels and more reliable terminal performance.

Are these bullets suitable for hunting?

Yes. Hornady SST bullets are specifically designed for hunting medium to large game, including whitetail, elk, antelope, moose, and similar-sized game. The controlled expansion and construction make them reliable for field use across a range of velocities.
