The Hornady 378 Weatherby Magnum Full Length Die Set is engineered for precision reloaders who demand accuracy and reliability in the field. Designed to fit Hornady Custom Grade Dies, these seating stems are machined to match the exact profiles of A-MAX, A-Tip, ELD Match, ELD-X, FTX, and MonoFlex bullets—ensuring perfect seating without bullet damage. (Not compatible with other manufacturers' dies.)

This set includes three essential reloading dies: a full-length sizing die, a bullet seating die, and an expanding die. Each die features Hornady’s innovative Zip Spindle™ design that locks securely to eliminate slippage, while the Sure-Loc™ lock rings provide consistent pressure across threads for a firm hold. The internal die profile is precision-machined and polished for smooth operation, preventing case sticking and excessive friction during resizing.

For superior neck sizing, the integrated elliptical expander reduces friction and minimises case neck stretch, outperforming traditional ball expanders. The seater adjustment screw allows quick bullet depth changes, and the in-line bullet seating system maintains perfect alignment between the bullet, case neck, and seating stem. A built-in crimper lets you crimp without an additional die, saving space on your press. The set comes in a compartmentalised box for convenient storage of dies, bushings, and shell holders.

Ideal for Australian shooters, hunters, and outdoor enthusiasts, this Hornady die set integrates seamlessly with your hunting gear, shooting optics, and tactical accessories. Available now from Xhunter Australia, it’s a durable and precise addition to any reloading bench or outdoor equipment setup.
