RCBS
The RCBS Matchmaster Competition Neck Bushing Set for 6mm GT gives precision reloaders the tools to fine-tune neck tension and maximize case life. Built from case-hardened steel with precision-drilled and hand-polished internal surfaces, this neck-size die set is built to the standards that benchrest and long-range shooters have relied on for years. The interchangeable neck bushings let you dial in exactly the amount of tension you need on your bullet, keeping brass working to a minimum and extending case longevity—a real advantage when you're processing brass for match-grade ammunition.
What sets the Matchmaster apart is attention to the details that matter when you're chasing groups. The seater die features an internal sleeve that catches and holds your bullet in perfect alignment, guiding it down the case for repeatable, concentric seating results. The loading window eliminates the fumble of balancing a bullet on the case mouth—drop it in and run the press. The oversized micrometer adjustment knob is engraved with large, easy-to-read letters and hash marks, so you can dial in your desired seating depth with confidence. A titanium carbonitride expander reduces brass buildup and ensures smooth extraction, and the free-floating, self-centering bullet seating stem keeps runout tight.
This is a neck-size set built in the USA and backed by RCBS's limited lifetime warranty. The 6mm GT is a modern, efficient cartridge gaining traction in precision rifle circles, and having a dedicated Matchmaster die set means you're set up for serious accuracy work without compromise.

The Matchmaster neck sizing die uses interchangeable neck bushings (sold separately) to control neck tension. The bushings are the critical adjustment point for fine-tuning how much grip your brass exerts on the bullet, so you'll want to have the right size for your exact needs.
This neck-size set includes the neck sizing die and bullet seating die. You will need to purchase the appropriate neck bushings separately to operate the sizing die.
The loading window with bullet retention system lets you simply drop a bullet in and run your press—no balancing or finger risk. The internal sleeve aligns and guides the bullet during seating, resulting in consistently concentric rounds.
The Matchmaster dies use the standard 7/8"-14 thread, so they're compatible with any press that accepts standard dies. Confirm your press threading before ordering.
