Hornady Single Full Length Sizer Die .300 PRC .308"

The Hornady Single Full Length Sizer Die for .300 PRC is a precision-engineered reloading die built for shooters who demand consistent case preparation and reliable performance across high-volume reloading sessions. Whether you're loading match ammunition for competition, preparing hunting rounds, or maintaining a serious handload operation, this full length sizer die handles the critical first step—bringing fired cases back to SAAMI spec so they chamber and fire safely and predictably.

Hornady's machining and polishing process keeps case flex smooth and friction low, so brass lasts longer and you spend less time fighting stuck cases. The die accepts .308" cases and integrates the Zip Spindle system, which locks tight to prevent creep while allowing quick, incremental adjustments—or large jumps—without disassembly. That's a practical feature when you're fine-tuning shoulder bump or switching between batches of brass. The Sure-Loc lock ring clamps the die body with wrench flats, holding zero without thread wear or the risk of pliers damage.

Inside, the elliptical expander (an exclusive Hornady design) outperforms traditional ball expanders: it sizes the neck more evenly, cuts friction, and reduces case neck stretch—all of which extend brass life and improve round-to-round concentricity. The smooth internal profile and precision finish mean cases feed without sticking, so your rhythm stays steady and your reloading bench stays efficient.

Built to Hornady's Custom Grade standard, this die carries their lifetime guarantee against breakage or wear under normal use—the kind of assurance that matters when reloading is central to your shooting discipline.

Frequently Asked Questions

Will this die work for reloading .300 PRC ammunition?

Yes. This Hornady Single Full Length Sizer Die is specifically designed for .300 PRC brass with a .308" case diameter, bringing fired cases back to proper SAAMI dimensions for reliable chambering and fire.

What's the difference between the Zip Spindle and a standard adjustment screw?

The Zip Spindle uses light threading on both the spindle and collet to lock positively and prevent slippage. You can make small incremental adjustments by turning the spindle, or quickly move it up or down for larger changes without disassembly—a practical advantage when switching between load batches or dialing in shoulder bump.

How does the elliptical expander improve brass life?

The elliptical expander sizes the neck more evenly than traditional ball expanders, reduces friction during the sizing stroke, and minimizes case neck stretch. Together, these characteristics help brass survive more reloading cycles and improve round-to-round consistency.

Is this die guaranteed?

Yes. Hornady backs this Custom Grade die with a lifetime guarantee against breakage or wear resulting from normal reloading use.
