The Redding 300 WSM Bushing Die Set is a three-die reloading solution built for handloaders who demand precision and consistency when assembling ammunition for the .300 Winchester Short Magnum. This complete die set pairs Redding's proven Type S bushing system with a competition-grade seating die, giving you the control needed to produce match-grade rounds for hunting or long-range shooting.
What sets this die set apart is the interchangeable bushing design. Rather than forcing you into a fixed neck diameter, the Type S bushings let you dial in neck tension in 0.001" increments—critical when you're working with quality brass and want to avoid over-working the case neck. The bushings are hardened steel and available with optional TIN (Titanium Nitride) coating for reduced friction and longer die life. Because they float freely, they self-center on the case neck, which means tighter, more uniform sizing and better shot-to-shot consistency downrange.
The competition seating die included in this set is purpose-built for precision ammunition assembly. Combined with the two bushing dies—one for full-length sizing and one for neck sizing only—you have genuine flexibility in how you approach each reload stage. Whether you're fine-tuning loads for a competition rifle, working up hunting rounds, or just maximizing the life of premium brass, this Redding set delivers the adjustability and repeatability that separates good loads from great ones.

Yes. The Type S bushing system lets you control neck diameter and tension in 0.001" increments by swapping bushings, giving you precise control without over-working your brass.
The bushings come in hardened steel. They are also available with a TIN (Titanium Nitride) coating option, which provides greater lubricity and can extend die life.
Yes. The inclusion of a competition-grade seating die and the precision-focused bushing system make this set well-suited for either application, provided you're loading for the .300 WSM cartridge.
