Special Features
- The Zip Spindle design positively locks to eliminate spindle slippage and allows fast tool-free incremental adjustments, removing the frustration and imprecision of conventional spindle lock systems
- The Elliptical Expander delivers smoother neck sizing with less friction and reduced case neck stretch than standard ball expanders, which is especially valuable when working with 300 Rem SAUM brass that can be difficult to source in volume
- 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 that the high-pressure 300 Rem SAUM demands for both accuracy and safe function
- 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 who need cases sized to minimum spec for reliable bolt closure in any 300 Rem SAUM chamber, particularly important given the short, fat case geometry of this cartridge
- Hunters loading the 300 Rem SAUM for elk, mule deer, or other big game at long range will get consistent, field-ready ammunition that delivers the high velocity and flat trajectory this cartridge was engineered to produce
- Handloading is essentially the most practical way to keep a 300 Rem SAUM in regular use, and this die set gives you the precision and repeatability needed to make every loading session count
- 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 Full Length 2-Die Set (546347) in 300 Remington Short Action Ultra Magnum is a reliable pick for any serious handloader committed to building accurate, hard-hitting ammunition for one of the most capable short-action 30-caliber cartridges ever produced.
