RCBS Matchmaster Full Length Bushing 2 Die Set 6mm GT

• Micrometer seating adjustment: The oversized micrometer lets seating depth changes be made in fine, repeatable increments, which helps when tuning loads for consistent jump and easier return to a proven setting.
• Full-length bushing sizing: The bushing-style sizing die gives direct control over neck tension while still sizing the full case body, making it well suited to precision rifle ammunition that must chamber reliably.
• Titanium carbide expander: The sizing die uses a titanium carbide expander to reduce brass buildup and promote smoother case extraction, which helps keep operation consistent over longer loading sessions.
• Standard 7/8"-14 thread: Compatibility with common reloading presses makes this die set easy to integrate into an established bench setup without special adapters.
• Made for 6mm GT precision loading: Built around the 6mm GT cartridge, this set combines precise bullet seating with controlled neck sizing for handloaders focused on concentric, repeatable rifle ammunition.

About the MatchMaster Series

The RCBS MatchMaster series sits at the precision-focused end of the company’s rifle die lineup. It is built for handloaders who want more control over the variables that affect consistency, especially neck tension, bullet seating depth, and cartridge alignment. Rather than following a general-purpose die format, MatchMaster dies are designed around the needs of shooters developing accurate loads for competition, long-range shooting, and carefully tuned hunting rifles.

A defining feature of the series is its combination of bushing-based sizing options and micrometer-adjustable seating. This gives the loader a more deliberate way to tune brass preparation and seating depth than with standard fixed-dimension dies. The MatchMaster seating die design also emphasizes straight bullet entry and repeatable adjustment, while the sizing dies are intended to deliver precise case preparation with less drag during operation. In practical terms, the series is aimed at reloaders who measure results closely and want a die set that supports systematic load development rather than simple volume loading.

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

The RCBS Matchmaster Full Length Bushing 2 Die Set 6mm GT is built for reloaders who want the case control of a full-length sizing die without giving up the tuning advantages of a bushing system. For the 6mm GT, that matters because the cartridge is widely chosen for accurate, efficient rifle loads where uniform neck tension and dependable chambering both play an important role. This set combines full-length sizing with bullet seating, making it a practical choice for shooters loading ammunition that must feed and chamber consistently while still being tuned for precision.

The sizing die uses a competition bushing full die set format and a titanium carbide expander. In use, that means the loader can select neck tension through the bushing system while benefiting from smoother operation and reduced brass buildup on the expander surface. The seating die adds an oversized micrometer adjustment, which is especially useful when comparing seating depths during load development or returning to a known setting after changing bullets. Because the set fits standard 7/8"-14 thread presses, it works easily with common single-stage reloading setups. The result is a steel two-die rifle set that supports careful, repeatable ammunition assembly for shooters who want more control than a conventional full-length die set typically provides.

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 started the business. From those beginnings, RCBS grew into a specialist in ammunition handloading and reloading equipment for both rifle and pistol cartridges.

RCBS is still based in Oroville, California, United States, and its product range covers the core tools of a reloading bench, including dies, presses, shell holders, powder measures, and priming tools. The brand is particularly well known for building equipment that serves everyone from first-time handloaders to experienced precision reloaders, with product lines that include single-stage, turret, and progressive presses. That long focus on practical reloading tools is directly relevant to products such as the MatchMaster die series.
