Precision Full Length Horn Die Set for 7mm WSM - 2-Piece Reloading Kit

The Hornady Precision Full Length Horn Die Set for 7mm WSM is a two-piece reloading kit built for shooters who demand consistency and durability at the bench. Whether you're developing loads for a precision rifle or fine-tuning factory ammunition, this die set gives you the tools to achieve repeatable, accurate results. Hornady's Series I dies are engineered with the bottleneck shooter in mind, and the 7mm WSM configuration delivers the reliability that serious reloaders have trusted for decades.

Built into these dies are features that reduce friction and case stress during the sizing and seating process. The elliptical expander—a Hornady exclusive—provides smoother neck sizing than traditional ball expanders and significantly reduces case neck stretch, a critical advantage when you're working toward benchrest precision. The in-line bullet seating system aligns the bullet, case neck, and seating stem in perfect alignment before the bullet enters the case, eliminating runout and inconsistency shot to shot.

The die set includes Hornady's Sure-Loc lock rings, which clamp around the entire die body and apply constant pressure across the threads without ever contacting them—eliminating the risk of thread damage from over-tightening. The Zip Spindle Design on the full length size die uses fine threads on both spindle and collet, letting you make incremental adjustments by hand or larger movements quickly. A built-in crimper on the seating die saves you a press station and gives you the option to crimp in a single step. Internal die profiles are precision-polished for smooth operation and minimal case sticking.

Both dies arrive in a compartmentalized box designed for organized storage of dies, bushings, and shell holders. Hornady backs these dies with a no-risk lifetime warranty against breakage or wear from normal use.

Frequently Asked Questions

What's included in this 7mm WSM die set?

The set includes two dies: a full length size die with elliptical expander and a bullet seater die with built-in crimper. You also get a compartmentalized storage box for organizing your dies and accessories.

Can I use the built-in crimper, or do I need a separate crimping die?

The seater die includes a built-in crimper, so you have the option to crimp without a separate die. This saves a station on your reloading press if you choose to use it. If you prefer not to crimp during seating, you can skip that step.

What makes the elliptical expander better than a standard ball expander?

Hornady's elliptical expander provides smoother neck sizing and significantly reduces friction and case neck stretch compared to ball expanders. The internal threading prevents it from pulling loose, and it can also eliminate the need for a separate expander die when necking up to the next caliber.

How do I adjust the die settings once they're locked in?

The Zip Spindle Design uses fine threads on both the spindle and spindle collet. You can make incremental adjustments by turning the spindle by hand, or zip it up or down quickly for larger movements. The Sure-Loc lock ring then clamps the die firmly in place without damaging the threads.
