RCBS Matchmaster Competition Full-Length Bushing Set for 7mm PRC (Model 28108)

The RCBS Matchmaster Competition Full-Length Bushing Set for 7mm PRC is engineered for serious reloaders who demand precision and consistency in every round. This full-length sizing and bullet seating system combines traditional craftsmanship with modern competition design, making it the choice for benchrest shooters, long-range hunters, and anyone committed to extracting maximum accuracy from their 7mm PRC ammunition. Built with case-hardened steel and hand-polished internal surfaces, the Matchmaster delivers the fit and finish you'd expect from a manufacturer with decades of precision reloading experience.

The sizing die uses interchangeable neck bushings (sold separately) to give you fine control over neck tension—a feature that's been trusted by precision shooters for generations. By dialing in exactly the right bushing diameter, you minimize unnecessary brass working, which extends case life and helps maintain the tight tolerances that separate good loads from great ones. The included Titanium Carbo Nitride expander reduces buildup on the expander and makes extraction smooth and reliable, shot after shot.

The bullet seating die is where the Matchmaster really shines for handloaders who care about concentricity. Its exclusive loading window and bullet retention system let you drop a bullet safely into the case mouth, then run the press—no balancing, no finger risk. The internal sleeve catches and centers the bullet before seating, guiding it with precision that translates directly to tighter groups downrange. The large oversized micrometer adjustment knob features legible hash marks and letters, and it's calibrated to dial in movements of one-thousandth of an inch with absolute repeatability.

The seater die is finished in a deep blue that reflects the quality you're investing in. Both dies feature standard 7/8"-14 threading and are manufactured in the USA, backed by RCBS's limited lifetime warranty.

Frequently Asked Questions

Do I need to buy neck bushings separately?

Yes. The Matchmaster sizing die uses interchangeable neck bushings (sold separately) so you can select the exact diameter that matches your needs and brass condition. This modular approach is a hallmark of the Matchmaster system.

Will this set work with my single-stage or turret press?

The dies feature standard 7/8"-14 threading, which is the universal standard for most reloading presses. Confirm your press accepts standard dies before ordering.

What's the advantage of the loading window on the seating die?

The loading window and internal bullet retention system allow you to safely drop a bullet into the case mouth, then run the press without manually holding the bullet in place. The retention system guides and centers the bullet for improved concentricity and eliminates the risk of fingers near the die.

Can I use the included Titanium Carbo Nitride expander with my current brass?

Yes. The Titanium Carbo Nitride expander is designed to reduce buildup on the expander itself, which can help maintain smooth extraction and extend the working life of your brass across multiple reloading cycles.
