RCBS Matchmaster Competition Neck Bushing Set 7Mm Rem Mag

The RCBS Matchmaster Competition Neck Bushing Set for 7mm Rem Mag brings precision reloading within reach of shooters serious about consistency and brass longevity. Built for handloaders who demand tight tolerances without unnecessary case wear, this neck-sizing system uses interchangeable bushings to control bullet tension with repeatable accuracy. The Matchmaster line has earned its reputation among benchrest and long-range competitors for a reason: meticulous manufacturing, thoughtful engineering, and components designed to work together seamlessly.

What sets the Matchmaster apart is attention to detail in both design and execution. The neck bushing system lets you dial in the exact amount of tension on your bullet, keeping brass working to a minimum and extending case life significantly—a real advantage when you're forming and fire-forming expensive magnum brass. The seater die features a loading window with an internal sleeve that catches and centers your bullet before seating, eliminating the awkward balancing act and the finger hazard of traditional methods. The result is consistently concentric rounds shot after shot.

These dies are machined from case-hardened steel with precision-drilled and hand-polished internal surfaces. The seater die wears a deep blued finish befitting a precision tool, and the oversized micrometer adjustment knob—marked with large, easy-to-read hash marks—lets you dial in one-thousandth of an inch and trust you'll get exactly that. The free-floating, self-centering bullet seating stem and titanium carbo-nitride expander round out a system built for shooters who treat reloading as seriously as they treat shooting. Standard 7/8"-14 threading means compatibility with any standard single-stage press.

Note: This set includes the neck sizing die and bullet seating die but requires separate neck bushings (sold separately) to establish your desired bullet tension. If you're building a 7mm Rem Mag precision handload, the Matchmaster neck bushing set is the foundation that delivers.

Frequently Asked Questions

Do I need to buy neck bushings separately?

Yes. This set includes the neck sizing die and bullet seating die, but neck bushings are sold separately. You'll need to select bushings matched to your desired bullet tension.

What press does this fit?

The Matchmaster dies use standard 7/8\"-14 threading, so they'll work with any single-stage reloading press with that standard thread.

How is the Matchmaster seater die different from a standard seating die?

The Matchmaster seater features a loading window with an internal sleeve that catches and aligns your bullet before seating. This eliminates the need to balance the bullet on the case mouth and delivers more concentric results. The oversized micrometer knob with large hash marks also makes precise adjustment easier to read and execute.

Why use a neck bushing system instead of full-length sizing?

Neck bushing sizing controls bullet tension while keeping overall brass manipulation to a minimum, which extends the life of your cases—a significant advantage for precision and competition handloading, especially with expensive magnum brass.
