Special Features
- The Zip Spindle design positively locks to eliminate spindle slippage and allows fast tool-free incremental adjustments, making seating depth changes quick and repeatable without the knuckle-busting effort of conventional spindle lock systems
- The Elliptical Expander delivers smoother neck sizing with less friction and reduced case neck stretch than standard ball expanders, extending the working life of your 300 Win Mag brass across more reloading cycles
- The In-line Bullet Seating System aligns the bullet, case neck, and seating stem inside a floating sleeve before the bullet enters the case neck, producing the consistent seating depth that long-range 30-caliber loads demand for accuracy at distance
- The built-in crimper on the seating die handles crimping without requiring a separate die or giving up an extra station on your press
- Sure-Loc lock rings clamp around the entire die body with constant pressure, keeping the locking screw off the threads to protect both die and ring from contact damage
- Hornady guarantees these dies will never break or wear out from normal use

- Your brass will load more smoothly and last longer with the hand-polished interior finish and Elliptical Expander reducing friction and neck stress on every pass through the sizing die
