COMP BUSHING DIE .308

The Redding Reloading Equipment Comp Bushing Die for .308 is purpose-built for competition shooters and handloaders who demand repeatable, precision neck sizing without a sizing button. If you're meticulously preparing match-grade ammunition and want full control over your neck diameter, this bushing die delivers the consistency that tight groups demand. The design philosophy centers on supporting your cartridge case completely before and during the sizing stroke—a feature that separates competition-grade equipment from standard dies.

What sets this .308 bushing die apart is its engineering approach to case control. The cartridge case sits in a tightly chambered, sliding sleeve that remains in firm contact throughout the entire sizing process. As the case moves upward, the sizing bushing self-centers on the case neck, maintaining alignment without relying on a button. The decapping rod is kept in precise alignment using the die's internal structure as a linear guide—similar to how a firing pin operates in a rifle chamber. This design minimizes case runout and delivers the sort of dimensional consistency competition shooters expect.

The micrometer adjustment on the bushing position puts you in control of exactly how much neck diameter gets sized, letting you dial in your setup rather than accept a one-size-fits-all approach. That granular control is what separates a die designed for precision reloading from a general-purpose tool. If you've already invested the time to sort, clean, and inspect your brass, a bushing die respects that work and rewards it with better ammunition.

Frequently Asked Questions

What's the difference between a bushing die and a standard sizing die?

A bushing die uses interchangeable bushings to size the case neck to a specific diameter, giving you precise control over how much material is sized. This .308 bushing die is designed without a sizing button, letting you control neck sizing via micrometer adjustment of the bushing position—ideal for competition shooters working with prepared brass.

Do bushings and a shellholder come with this die?

No. Bushings and shellholders are sold separately, allowing you to select the exact components your reloading setup requires.

What kind of shooter is this die designed for?

This is a competition-grade die built for handloaders who have meticulously prepared their cartridge cases and want precise, repeatable neck sizing without relying on a sizing button. It's suited to shooters focused on match-grade ammunition and tight dimensional control.

Can I use a sizing button with this die?

This die is designed for use without a sizing button. However, Redding offers carbide size button kits available separately if you choose to add that functionality.
