Precision Full-Length Horn Die Set for 338 Win Mag Reloading

The Hornady Precision Full-Length Horn Die Set for 338 Win Mag is built for reloaders who demand consistency and reliability in bottleneck rifle cartridge ammunition. This two-die set pairs a full-length sizing die with a bullet seater, giving you the core tools needed to load match-grade rounds for your magnum rifle. Whether you're loading for long-range hunting, precision rifle competitions, or target practice, Hornady's Series I dies are engineered to eliminate the friction and case-sticking issues that can slow your workflow and compromise accuracy.

At the heart of this set is Hornady's Zip Spindle Design—a mechanism that locks positively to your press to prevent slippage during sizing. Fine threads on both spindle and collet let you make micro-adjustments for incremental changes, or zip the die up and down for larger movements without fussy re-threading. The sizing die's internal profile is precision machined and polished to a smooth finish, reducing friction and the case sticking that haunts less-refined dies. An elliptical expander—Hornady's exclusive over ball expanders—sizes your case neck with minimal stretch and exceptional smoothness.

The seater die features Hornady's In-line Bullet Seating System, which aligns the bullet and case neck in perfect alignment before the bullet ever enters the case neck. This pre-alignment translates directly to runout control and the kind of concentricity that precision shooters rely on. A built-in crimper option eliminates the need for a separate crimp die, freeing up a station on progressive or turret presses. The Sure-Loc lock rings clamp the entire die body and tighten via a screw that never contacts the threads, protecting your investment from damage.

Every set arrives in Hornady's compartmentalized, stackable storage box with clear labeling—keep your 338 Win Mag setup organized alongside your other reloading dies. Hornady backs the entire set with a lifetime no-risk warranty against breakage or wear from normal use.

Specifications

Frequently Asked Questions

What press compatibility does this die set have?

Hornady Series I dies are standard 7/8-14 threaded dies and will fit any reloading press equipped with standard die stations. The Zip Spindle Design locks positively to your press to prevent slippage.

Do I need a separate crimper die?

No. This set includes a built-in crimper in the seater die, so you have the option to crimp without purchasing a separate crimp die. This frees up a station on your press if you're running a progressive or turret model.

What's included in the die set box?

Each set comes in a compartmentalized, stackable storage box containing the sizing die, seater die, shell holders, bushings, and a taper crimp die, with clearly labeled sections to keep everything organized.

Will this set work for long-range hunting load development?

Yes. The In-line Bullet Seating System aligns bullets and case necks for optimum concentricity, and the elliptical expander delivers smooth, consistent neck sizing—both critical for the precision and consistency needed in long-range ammunition.
