RCBS Matchmaster Full Length Bushing 2 Die Set 6mm Dasher

• Interchangeable neck-bushing system: The MatchMaster full-length sizing die uses changeable bushings so neck tension can be tuned to the brass, bullet and load. That gives the handloader tighter control over bullet release, which is especially useful when chasing low extreme spread and repeatable long-range accuracy.
• Micrometer seating adjustment: The seating die uses a micrometer-style adjustment that makes fine seating-depth changes easy to repeat. This is practical for load development, where small changes in jump can matter and returning to a proven setting saves time.
• Full-length sizing for reliable chambering: This 2-die set combines precision neck-tension control with full-length sizing, helping 6mm Dasher cases feed and chamber consistently while still supporting match-grade ammunition assembly.
• Titanium carbide sizing-die construction: The sizing die uses titanium carbide in a steel die body to reduce wear in a high-use precision reloading setup. The result is a durable working surface that supports smooth, consistent case sizing over many loading cycles.
• Standard 7/8"-14 press compatibility: The dies fit presses that use the common 7/8"-14 thread, making it easy to integrate this set into an established single-stage or turret reloading bench without special adapters.

About the MatchMaster Series

RCBS MatchMaster dies sit at the precision end of the company’s rifle-die lineup, built for reloaders who want more control over seating depth, neck tension and case sizing than a conventional hunting die set normally provides. The series is aimed at precision rifle, benchrest and long-range handloading, where small changes in setup can show up on target.

A defining feature of the series is its use of interchangeable neck bushings in the sizing die, allowing the loader to tune neck tension for a specific brass lot or bullet choice instead of accepting a fixed internal dimension. MatchMaster seating dies also emphasize repeatability through micrometer adjustment, which makes it easier to test seating-depth changes and return to a known load setting later. RCBS positions the series as a premium steel-die system with careful internal finishing and a design focused on concentric ammunition, consistent bullet alignment and repeatable die settings. In practice, that makes the MatchMaster family a strong fit for shooters developing loads for small groups, stable velocity and dependable performance at extended distance.

About the RCBS Matchmaster Full Length Bushing 2 Die Set 6mm Dasher

The RCBS Matchmaster Full Length Bushing 2 Die Set 6mm Dasher is built for reloaders who want match-style control in a cartridge widely used for precision shooting and low-recoil long-range competition. Its combination of a full-length sizing die and a bullet seating die gives the handloader the two core operations needed to produce consistent 6mm Dasher ammunition while keeping setup straightforward.

The full-length die uses the MatchMaster bushing system, so neck tension can be adjusted by selecting the appropriate bushing rather than relying on a one-size-fits-all neck dimension. That matters when brass thickness varies between lots or when a particular bullet performs best with a specific amount of grip. Full-length sizing also helps maintain reliable chambering, which is important for rifles that are run hard in competition or for shooters who want consistent bolt feel from one firing cycle to the next.

The seating die adds micrometer adjustment, making fine seating-depth changes easier to track during load development. For a cartridge such as 6mm Dasher, where shooters often tune bullet jump carefully, that repeatability is a practical advantage rather than a convenience feature. The die set uses a steel body, a titanium carbide sizing-die material and standard 7/8"-14 thread compatibility, so it fits naturally into a serious reloading bench while supporting long service life and precise adjustment.

About RCBS

RCBS was founded in 1943 by Fred T. Huntington in Oroville, California. The company name came from “Rock Chuck Bullet Swage,” the original bullet-swaging die that launched the brand. From that starting point, RCBS grew into a specialist in ammunition handloading and reloading equipment for rifle and pistol cartridges.

RCBS is known for building a broad reloading system rather than only individual tools. Its product range includes presses, dies, shell holders, powder measures and priming tools, with single-stage, turret and progressive press options for different loading styles. That long focus on reloading equipment is what makes the brand especially relevant in a product such as the MatchMaster die series, where precise adjustment, durable tooling and repeatable ammunition assembly matter most.
