Redding Type S Bushing Neck Die Set .300 Win Mag
$124.99
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.

Frequently Asked Questions
What dies are included in this set?
The set contains a Type S bushing-style neck sizing die, a regular series seating die, a standard decapping button, and a decapping pin retainer.
Can I use this die for full-length sizing or just neck sizing?
This is a neck sizing die set. The adjustable decapping rod allows you to control how much of the neck length is resized—you can work just the upper portion if desired—but the die is designed primarily for neck sizing work.
What are the interchangeable bushings used for?
Redding supplies sizing bushings in .001-inch increments, allowing you to select the exact bushing size that delivers your preferred bullet tension. Different bushings give you control over how tightly the resized neck grips the bullet.
Can I use this with commercial brass straight out of the box?
Yes. The set includes a standard decapping button, which is especially useful if you're loading commercial brass as-is without additional case prep. The decapping pin retainer also enables neck sizing without the button if you prefer to sort or turn case necks for uniformity.
