The Hornady 546244 Custom Grade Series I 2-Die Set for 243 Win delivers the precision and durability serious reloaders expect from a rifle die set built to exacting standards. This two-die set—consisting of a full-length sizing die and a bullet seating die—handles the core operations for consistent, accurate ammunition. Hornady backs every die with a lifetime warranty against breakage or wear under normal use, reflecting the quality of the manufacturing and design you're getting.
Built into the sizing die is Hornady's Zip Spindle Design, which locks firmly to the press to eliminate slippage during operation. Fine threads cut on the spindle allow you to dial in incremental adjustments or make quick large movements as needed. The internal profile is precision-machined and polished smooth, preventing case sticking and friction that can lead to inconsistent results. The Sure-Loc lock ring clamps around the entire die and holds position without the locking screw ever touching the threads—eliminating risk of damage and ensuring the die stays put through your entire reloading session.
The seating die incorporates Hornady's in-line bullet seating system, which aligns the bullet and case neck before the bullet enters the die for benchrest-level precision. The elliptical expander—superior to ball expanders—sizes the neck smoothly and reduces friction and case stretch. A built-in crimper eliminates the need for a separate crimp die, freeing up a station on your press. Seating depth adjusts easily via the adjustment screw, and the retainer ring comes free in seconds for quick cleaning and maintenance.
Dies arrive in a compartmentalized box with room for dies, bushings, shell holders, and accessories, keeping your setup organized and your equipment protected.
