Hornady SST 25 Cal 117-Grain InterLock Polymer Tip Spitzer Bullets - Box of 100

The Hornady SST 25 Cal 117-grain InterLock polymer tip spitzer bullets are built for reloaders who demand both speed and accuracy downrange. Whether you're building handloads for varmint hunting, medium-game pursuits, or long-range target work, these bullets combine a sleek polymer tip with a proven InterLock construction to deliver consistent performance and reliable expansion across a wide velocity range. The 117-grain weight in .25 caliber strikes a practical balance between aerodynamic efficiency and impact energy, making them a straightforward choice for hunters who want to reload with confidence.

The SST design starts with a polymer tip that boosts ballistic coefficient—meaning flatter trajectories and less wind drift between you and your target. That same tip acts as a wedge upon impact, initiating controlled expansion without relying on velocity alone. The secant ogive boattail profile further refines the ballistics, allowing the bullet to carry energy farther and shoot faster, which is especially useful when distance or wind become factors. The cannelure provides a consistent seating surface for crimping and works hand-in-hand with the InterLock ring to manage expansion behavior.

The InterLock ring is the real workhorse here—it mechanically locks the lead core to the copper jacket so they expand as one unit rather than separating on impact. This controlled expansion creates a larger wound channel while retaining enough bullet mass to penetrate reliably. For reloaders building ammunition for North American game or target applications, that combination of retained weight, velocity, and wound channel is what separates a quick, ethical harvest from a long tracking job.

You get 100 bullets per box, so one purchase supplies a solid batch of handloads. These are unprimed, unloaded components—just the bullets themselves—so you'll pair them with your choice of brass, primers, and powder to dial in your load.

Frequently Asked Questions

What calibers and rifles can use these .25 caliber bullets?

These are .25 caliber bullets (257 diameter). They're designed for rifles chambered in .25 caliber cartridges such as .25-06 Remington, .250 Savage, or other .257-diameter rifle rounds. Always verify your rifle's chamber specification before loading.

Are these finished cartridges or reloading components?

These are reloading components—bullets only. You'll need to pair them with brass cases, primers, and powder to create complete ammunition. Each box contains 100 unloaded, unprimed bullets.

What is the InterLock ring and why does it matter?

The InterLock ring is a mechanical lock that bonds the lead core to the copper jacket. This keeps them together during expansion, which ensures the bullet retains mass and energy to create a larger wound channel and more reliable penetration on game.

What game are these bullets suitable for?

The SST design and 117-grain weight in .25 caliber are appropriate for varmints, small-to-medium game, and target applications. Actual suitability depends on your specific rifle, load development, and local hunting regulations. Always consult ballistics data and hunting guides for your intended game and distance.
