Hornady Full Length Two-Die Set for 300 WSM Reloading
The Hornady Full Length Two-Die Set for 300 WSM Reloading gives you the core dies needed to resize and seat bullets for your 300 Winchester Short Magnum rounds. This two-piece setup—a full length size die and a bullet seater die—handles the two most essential operations in the 300 WSM reloading process. Whether you're fine-tuning handloads for precision hunting or building match-grade ammunition at the bench, Hornady's Series I design delivers the control and reliability that serious reloaders expect.
The full length size die features Hornady's Zip Spindle Design, which locks positively to the press ram and eliminates slippage during the sizing stroke. Light threads cut on both the spindle and spindle collet let you make micro-adjustments by turning the spindle, or zip it up and down quickly for larger movements. The internal die profile is precision-machined and polished smooth, so cases move through without sticking or excess friction—a detail that adds up over hundreds of rounds. The Sure-Loc lock ring clamps around the entire die body with constant pressure, held by a locking screw that never contacts the threads, so you won't accidentally strip or damage the fit.
The seater die uses Hornady's in-line bullet seating system, which aligns the bullet and case neck before the bullet ever enters the case for benchrest-grade concentricity. A floating bullet alignment sleeve and floating steel seating stem work together to center every round. The built-in crimper lets you apply a taper crimp without running a separate die, freeing up a station on your press if you're running a turret or progressive loader. Seating depth adjustment is straightforward via the adjustment screw, and the locking retainer ring removes in seconds if you need to clean or maintain the die.
Hornady backs this set with a no-risk lifetime warranty against breakage or wear under normal use, and both dies ship in a compartmentalized box designed to keep your reloading gear organized and accessible.
