Redding Competition Bushing Neck Die 243 Win

The Redding Competition Bushing Neck Die for 243 Win gives precision reloaders the control they need to achieve consistent, tight neck dimensions on competition ammunition. Built around Redding's proven bushing-style design, this die is engineered for shooters who've already invested time in quality case prep and want to avoid the extra work—and potential runout—that comes with a sizing button. If you're loading match rounds and chasing the smallest groups possible, this die lets you size the neck to your exact specifications.

The die's engineering centers on complete case support and alignment from start to finish. Your cartridge case sits in a precisely machined, sliding sleeve that keeps it anchored and straight as the resizing bushing does its work. The bushing self-centers on the case neck as you raise the ram, eliminating the guesswork and ensuring uniform sizing every time you pull the handle. The decapping rod stays locked in perfect alignment thanks to the die's internal geometry—think of it like a firing pin's guidance system. That kind of support matters when you're working with cases you've already refined.

The real game-changer is the micrometer adjustment on the bushing position. Instead of swapping bushings or eyeballing it, you dial in exactly how much neck sizing you want. That level of precision is what separates competition dies from general-purpose tools. Keep in mind that bushings and shellholders are sold separately, so plan your order accordingly.

Frequently Asked Questions

Do I need a carbide sizing button with this die?

No—the Competition Bushing Neck Die is designed for reloaders who prefer not to use a sizing button. Carbide button kits are available separately if you change your mind later.

What's included, and what do I need to buy separately?

The die itself is included. Bushings and shellholders are sold separately, so you'll need to order those to complete your setup.

Who should use this die?

This is built for competition shooters and precision reloaders who have already invested in case preparation and want direct, repeatable control over neck sizing without a button.

How does the bushing self-centering work?

As you raise the ram, the cartridge case is held in a tightly chambered, sliding sleeve that keeps it aligned. The resizing bushing self-centers on the case neck as it moves upward, eliminating the variables that come from hand positioning.
