The Redding Type S Bushing Neck Die Set for .300 Win Mag gives precision reloaders a purpose-built system for controlling case neck sizing and bullet tension with repeatable accuracy. This two-die set pairs a bushing-style neck sizing die with a standard seating die, letting you fine-tune the fit of your rounds without the guesswork that comes with generic one-size-fits-all dies. Whether you're running premium match brass or sorting and prepping commercial cases, the Type S design adapts to your process.
The heart of this system is the interchangeable bushing concept. Redding supplies sizing bushings in .001-inch increments, so you can dial in the exact neck tension your ammunition demands. The bushing self-centers on the case neck during sizing, which means better concentricity and more consistent bullet runout—critical for accuracy-focused handloading. The included adjustable decapping rod lets you choose how much of the neck to resize; you can work just the upper portion if you prefer a gentler sizing approach or have done your own case neck work.
This set comes equipped with a standard decapping button and a decapping pin retainer, giving you flexibility in how you approach your prep work. Neck sizing without the button is straightforward once the pin retainer is in place, which appeals to reloaders who turn case necks or sort brass for uniformity. The Type S design is straightforward to set up and integrates easily into a single-stage or progressive press.
