Redding 300 Wsm Bushing Die Set

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.
