Special Features
- The Zip Spindle design positively locks to eliminate spindle slippage and allows fast tool-free incremental adjustments, removing the frustration of conventional spindle locks that require over-tightening to hold position
- The Elliptical Expander delivers smoother neck sizing with less friction and reduced case neck stretch than standard ball expanders, especially important when working with the long, belted 300 H&H case that can be difficult to source and expensive to replace
- 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 consistent seating depth across every round loaded for a cartridge where accuracy and reliability matter most
- The built-in crimper on the seating die gives shooters who prefer a roll crimp for magazine security the option to apply one without adding a separate die or extra press station
- 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
Practical Benefits
- The full-length sizing die makes this set the right choice for reloaders working with belted magnum brass that needs to be sized to minimum spec for reliable bolt closure in any 300 H&H chamber
- Hunters and vintage rifle owners loading the 300 H&H Magnum for large or dangerous game will get consistent, field-ready ammunition that performs with the authority this cartridge was designed to deliver
- The Series IV designation covers specialty and less common cartridges like the 300 H&H, and this die set gives those rifle owners the same Custom Grade precision available to shooters of modern mainstream calibers
- 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
The Hornady Custom Grade Series IV Full Length 2-Die Set (546346) in 300 Holland and Holland Magnum is a dependable option for any serious handloader building accurate, hard-hitting ammunition for a classic and capable big bore cartridge.
