The RCBS 11104 MatchMaster Duo Set for .223 Remington pairs two essential reloading dies in one package, designed for handloaders who need repeatable precision without fuss. This set combines RCBS's MatchMaster Seating Die—built with micrometer-adjustable depth control for shot-to-shot consistency—with a full-length sizing die that handles case preparation the traditional, proven way. If you're loading .223 for precision rifle work, competition shooting, or high-volume practice, the Duo delivers match-grade performance without requiring external bushings or complicated setup.
RCBS engineered this set around the principle that precision reloading shouldn't demand a learning curve or exotic accessories. The MatchMaster Seating Die's micrometer adjustment lets you dial in bullet seating depth to the tenth of an inch, then lock it in and trust it—shot after shot. The full-length sizing die conditions your brass for consistent chamber fit, which is especially important when you're working with .223 cases that might cycle through multiple rifles. Together, they form a complete die set ready to integrate into any standard reloading press.
Made in the USA and backed by RCBS's reputation in the reloading world, this set is built to handle volume and deliver the kind of consistency that separates good handloads from match-grade ammunition. Whether you're fine-tuning loads for a precision bolt gun, running a semi-auto platform, or pursuing sub-MOA accuracy on the range, the MatchMaster Duo gives you the tool set to get there.

Frequently Asked Questions
What's included in the MatchMaster Duo Set for .223?
The set includes a MatchMaster Seating Die with micrometer adjustment and a full-length sizing die, both sized for .223 Remington. These are the two dies you need for a basic reloading cycle—sizing and seating.
Do I need shell holders or bushings to use this set?
The MatchMaster Duo does not require bushings. You will need a shell holder that matches .223 Remington (sold separately), which indexes your case in the press.
Is this die set suitable for both bolt-action and semi-auto .223 rifles?
Yes. The full-length sizing die will size brass for use across different .223 rifles. The micrometer seating die allows you to adjust for slight variations in overall length or chamber fit between rifles.
What does the micrometer adjustment on the seating die do?
The micrometer lets you set and repeat bullet seating depth to within a tenth of an inch. Once you dial in your target depth, you can lock it in and seat every bullet to the same depth—critical for precision handloading.
