Rcbs Matchmaster Competition Neck Bushing Set 6Mm Dasher
$177.34
The RCBS Matchmaster Competition Neck Bushing Set for 6mm Dasher gives precision reloaders the ability to dial in consistent neck tension—a critical factor in accuracy-focused rifle ammunition. This set includes both a neck sizing die and bullet seating die, with interchangeable neck bushings that let you control exactly how tightly the case neck holds the bullet. If you're handloading for competition, long-range hunting, or benchrest shooting, this level of control over case prep is what separates mediocre groups from repeatable precision.
Each die is machined from case-hardened steel with precision-drilled and hand-polished internal surfaces. The sizing die features a titanium carbo-nitride expander that reduces brass buildup and makes extraction smooth—an often-overlooked detail that extends case life when you're fireforming or working with tight tolerances. The seating die is where Matchmaster really shines: an oversized micrometer adjustment knob with clear markings lets you dial in bullet seating depth to the thousandth of an inch with confidence. The integrated loading window and internal bullet-retention sleeve center the projectile automatically, eliminating the awkward balancing act and finger-risk of older seating dies while ensuring concentricity shot after shot.
This is a neck-size-only set, which means minimal case work—perfect if you're preparing brass for a precision rifle where case longevity and consistency matter. Standard 7/8"-14 thread compatibility keeps this compatible with most single-stage and turret presses. Made in the USA and backed by RCBS's limited lifetime warranty, the Matchmaster is built for reloaders who understand that the investment in quality dies pays dividends in ammunition consistency and case life.

Frequently Asked Questions
What neck bushings do I need for this die set?
The set allows you to use interchangeable neck bushings to control bullet tension, but the bushings are sold separately. You'll select the bushing diameter based on your target neck tension and case preparation.
Is this a full-length or neck-size-only set?
This is a neck-size-only set, designed for reloaders who are working with prepared brass and want minimal case manipulation to extend case life and maintain consistency.
Will this work with my single-stage press?
Yes. The dies use the standard 7/8"-14 thread, compatible with most single-stage and turret reloading presses.
What does the titanium carbo-nitride expander do?
The titanium carbo-nitride expander reduces brass buildup on the expander itself and provides smooth case extraction, helping extend the life of your brass cases during the resizing process.
