Special Features
- Zip Spindle design uses a series of light threads on both the spindle and collet so you can make fine incremental adjustments by turning or zip the spindle up and down quickly for larger movements without slippage.
- Elliptical expander reduces friction and stretching during case neck expansion, which extends brass life and produces more uniform neck tension across your loaded rounds.
- Hardened steel decapping pin resists bending and breaking even when punching out crimped military primer pockets.
- Sure-Loc lock rings clamp around the full die body and use a locking screw that never contacts the press threads, protecting both die and press from damage.
- In-line bullet seating system holds the bullet, case neck, and seating stem in precise alignment inside the sleeve before the bullet enters the case neck for improved concentricity.
- Built-in crimper in the seating die gives you the option to apply a roll or taper crimp during seating or run the die without crimp as your load demands.
- Locking retainer spring on the seating die removes in seconds for fast disassembly and cleaning without tools.
Practical Benefits
- This Hornady Custom Grade 300 WSM 2-Die Set (546369) fits reloaders who want a matched full length sizing and seating solution for brass that chambers reliably in bolt action rifles and feeds consistently from box magazines.
- Full length sizing brings fired brass back to spec whether you are working with once-fired brass from your own rifle or mixed headstamp brass from the range.
- The in-line seating sleeve and elliptical expander work together to give your finished 300 Winchester Short Mag rounds tight tolerances and consistent bullet runout, which pays off in tighter groups at distance.
- Compatible with standard 7/8 by 14 presses, this set works with virtually every single stage, turret, and progressive press on the market today.
- If you reload for a 300 WSM rifle used in the field or at the bench, the Hornady Custom Grade Series I 300 Winchester Short Magnum 2-Die Set (546369) is a proven platform for building consistent, accurate ammunition season after season.
