Redding Type S Bushing Neck Die 7Mm Rem Mag

The Redding Type S Bushing Neck Die for 7mm Rem Mag gives reloaders precise, repeatable control over case neck sizing and tension—critical for consistent accuracy and brass longevity. If you're building match-grade ammunition or simply want tighter control over your handloads than standard full-length sizing offers, this die solves the problem through a modular bushing system that lets you dial in exactly the fit you need.

The heart of the Type S design is its interchangeable sizing bushing, available in .001" increments, so you can match the bushing to your brass and bullet combination without guesswork. The bushing self-centers on the case neck during sizing, which means better concentricity—a real advantage when you're trying to wring out precision. An adjustable decapping rod lets you control how much of the neck gets resized; you can size only the upper portion if you prefer, which is especially handy if you're working with commercial brass or have already sorted and uniformed your necks for consistency.

The die ships with a standard decapping button and a decapping pin retainer, giving you flexibility in how you use it. If you're the type to turn necks or sort brass for uniformity, you can neck size without the button entirely—the retainer makes that setup simple. For 7mm Rem Mag reloaders who want to move beyond one-size-fits-all dies, the Type S is built for the meticulous approach.

Frequently Asked Questions

What's the difference between a Type S bushing die and a standard full-length sizing die?

A Type S die sizes only the neck, while full-length dies size the entire case body. The bushing system gives you precise control over neck tension in .001" increments, and the bushing self-centers for better concentricity. This is especially valuable if you're working with premium or sorted brass and want to maximize accuracy.

Do I need to buy bushings separately, or does the die come with what I need to start?

The die ships with a standard decapping button and pin retainer. Interchangeable bushings are available separately in .001" increments, so you can find the exact fit for your brass and bullets.

Can I use this die if I neck-turn my brass?

Yes—that's one of the Type S's strengths. The included decapping pin retainer lets you neck size without using the decapping button, making it straightforward to work with sorted or neck-turned brass.

What brass works best with this die?

The Type S works well with both commercial and premium brass. If you're using commercial brass as-is, the standard decapping button handles it. If you prefer to sort, turn, or uniform your necks, the retainer setup gives you the option to skip the button entirely.
