The Hornady Custom Grade Series I 2-Die Set for 300 Win Mag gives precision reloaders a proven, no-frills setup for bottleneck rifle cartridges. This two-die configuration pairs a full-length sizing die with a bullet seater die, handling the core operations you need to produce accurate, consistent ammunition. If you're loading for a 300 Winchester Magnum—whether for long-range hunting, precision rifle competition, or serious range work—this set delivers the control and reliability Hornady is known for.
The sizing die uses Hornady's Zip Spindle Design, a threaded system that lets you fine-tune case sizing with small adjustments or make bigger changes by hand. The internal profile is smooth and polished to reduce friction and case sticking, so your cases move through without fighting resistance. An elliptical expander (not a ball expander) smoothly sizes the case neck with minimal friction and stretch—a small detail that adds up over hundreds of rounds. The Sure-Loc lock ring clamps firmly around the die threads and won't loosen during pressing, and its wrench flats mean you don't need pliers that can damage the ring.
The seating die incorporates an in-line bullet alignment system that centers the bullet and case neck before the bullet enters, resulting in more consistent seating depth and better accuracy potential. A built-in crimper lets you finish your rounds without a separate die. Seating depth adjustment is straightforward, and the retainer ring pops out for quick cleaning. Hornady backs the set with a lifetime warranty against breakage or wear from normal use.
