RCBS Matchmaster Competition Full-Length Bushing Set 6mm ARC - Model 28008

The RCBS Matchmaster Competition Full-Length Bushing Set for 6mm ARC is built for shooters who demand precision in every round. This full-length reloading die set brings the benchrest and long-range competition pedigree of the Matchmaster line to the 6mm ARC cartridge, giving you the tools to maintain tight case tolerances and produce match-grade ammunition. Whether you're tuning loads for precision rifle competition, long-range hunting, or specialized shooting applications, the adjustable neck bushing system lets you dial in exactly the amount of bullet tension you need without unnecessarily working your brass.

Each die in the Matchmaster set is case-hardened steel with precision-drilled and reamed internal surfaces, hand-polished to exacting standards. The full-length sizing die accepts interchangeable neck bushings (sold separately), a proven system used by competitive shooters for years to achieve consistent case dimensions and extend brass life. The seater die is machined and deep-blued like a quality firearm, and features RCBS's exclusive loading window—a safety-first design that lets you drop the bullet and run the press without balancing rounds or risking your fingers. The internal sleeve aligns and guides each bullet for concentric seating.

The oversized adjustment knob on the seater die is marked with large, readable hash marks and letters, so you can dial in bullet seating depth with confidence. Precision reloaders appreciate that adjustment—turn one-thousandth of an inch, and that's exactly what you get. This is the kind of die set that rewards attention to detail, whether you're hand-loading for a precision competition rifle or a specialized hunting setup.

Frequently Asked Questions

Does this set include interchangeable neck bushings?

This is a bushing-compatible die set; neck bushings are sold separately. The bushing system allows you to swap different diameter bushings to fine-tune the amount of tension applied to your bullets.

What is the loading window feature and why does it matter?

The exclusive loading window in the seater die lets you insert the bullet into the case as you lower the ram, and an internal sleeve catches and aligns it during the seating stroke. This design eliminates the need to balance bullets on case mouths and keeps your hands safer during the loading process while improving seating concentricity.

Can I adjust bullet seating depth precisely with this die?

Yes. The Matchmaster seater die features a large, oversized adjustment knob with clear hash marks and letters. You can dial in seating depth in one-thousandth-inch increments for the consistency required in precision rifle loading.

Is this a full reloading die set or just a seater?

This is a complete full-length bushing set for 6mm ARC, which includes the sizing and seating dies you need for a full reloading cycle.
