Hornady SST 30 Cal 125 Grain InterLock Polymer Tip Spitzer Bullets - Box of 100

The Hornady SST 30 Cal 125 Grain InterLock Polymer Tip Spitzer Bullets deliver the combination of speed, accuracy, and reliable expansion that reloaders depend on for hunting medium game across North America. Built around Hornady's proven InterLock design and polymer-tipped construction, these bullets are engineered to expand consistently while maintaining structural integrity through the entire wound channel. Each box contains 100 bullets ready to load into your .30 caliber rifle cartridges.

What sets the SST apart is its dual-purpose design. The polymer tip isn't just aerodynamic—it initiates controlled expansion the moment the bullet strikes game, while the InterLock ring mechanically bonds the bullet's core and jacket to prevent premature separation. This means retained mass and energy transfer, the hallmarks of effective terminal performance on deer, antelope, and similar-sized game. The secant ogive boattail profile maximizes ballistic efficiency, so your handloads shoot flat and hit hard downrange. A cannelure is included for secure crimping and works in concert with the InterLock system to govern expansion reliably across a range of impact velocities.

If you're working up loads for .30-30, .308 Winchester, .30-06 Springfield, or other .30 caliber rifle cartridges, the SST's lightweight 125-grain construction makes it versatile for everything from close-range hunting to extended-distance work. Reloaders appreciate Hornady's consistency in these components—uniform jacket thickness, reliable bullet-to-bullet performance, and the engineering that makes the InterLock system work as intended. This is proven ammunition component technology backed by decades of hunting success.

Frequently Asked Questions

What .30 caliber cartridges can I use these bullets in?

The Hornady SST 30 Cal 125 grain is designed for .30 caliber rifle cartridges. Common applications include .30-30 Winchester, .308 Winchester, .30-06 Springfield, and similar .30 caliber centerfire rounds. Always verify that your specific cartridge and load data are compatible with a 125-grain bullet before reloading.

How does the InterLock ring control expansion?

The InterLock ring mechanically locks the bullet's copper jacket to the lead core. During expansion, this bond keeps the jacket and core from separating, which preserves bullet mass and energy transfer, resulting in a larger and more reliable wound channel compared to bullets without this feature.

Is the polymer tip necessary for the bullet to expand reliably?

The polymer tip serves two purposes: it improves the bullet's aerodynamic profile (ballistic coefficient) and it initiates controlled expansion upon impact. The InterLock ring is the primary expansion control system, but the polymer tip complements it by starting the expansion process consistently across different impact velocities.

What game is the 125-grain SST suitable for?

Hornady's SST line is designed for hunting deer, antelope, and similar medium-sized game animals. The 125-grain weight in .30 caliber is optimized for these applications. Always select a bullet weight and construction appropriate to your intended game and shooting distance.
