RCBS
The RCBS MatchMaster Duo Set for 6mm Creedmoor pairs precision seating control with reliable full-length sizing—two essential tools for handloaders chasing competitive accuracy or hunting consistency. This matched die set combines RCBS's micrometer-adjustable MatchMaster Seating Die with a conventional Full-Length Sizing Die, giving you the flexibility to dial in your exact seating depth while maintaining proper case dimensions. Whether you're loading rounds for long-range competition, precision hunting, or load development, the Duo Set is designed to work together without requiring bushings, streamlining your reloading bench setup.
6mm Creedmoor has earned a solid reputation as a flat-shooting, barrel-friendly cartridge for precision rifle competitors and hunters who want inherent accuracy without the recoil of larger magnums. This die set is purpose-built for that cartridge, so you're not adapting a generic solution. The MatchMaster Seating Die lets you make repeatable, fine adjustments—critical when tight velocity spreads and consistent bullet seating depth directly affect group size. The full-length sizer handles case preparation the traditional way, restoring brass to spec after firing so it chambers cleanly and safely on every reload.
RCBS has been manufacturing reloading dies in the USA since 1956, and this set carries that proven heritage. It's designed for serious handloaders who understand that precision is built through consistent processes, not shortcuts. Come ready to load—no additional dies, bushings, or accessories needed to get started.

| Model Number | 31804 |
| Cartridge | 6mm Creedmoor |
| Die Type | Full-Length Sizing Die + MatchMaster Seating Die |

The MatchMaster Duo Set includes an RCBS MatchMaster Seating Die with micrometer adjustment and an RCBS Full-Length Sizing Die—everything you need to size fired cases and seat bullets. No additional bushings or components are required.
Yes, this set is chambered specifically for 6mm Creedmoor. RCBS offers MatchMaster Duo sets in other popular cartridges, but this model is sized for that cartridge alone.
While the dies are sold as a matched pair, each performs its own function. The seating die handles bullet seating depth; the full-length sizing die prepares fired brass. Most precision reloaders use both in sequence as part of their reloading process.
RCBS backs this set with a Limited Lifetime Warranty, honoring the quality and durability of these USA-made tools.
