The RCBS MatchMaster Competition Seating Die for .22 CM brings precision handloading to your rifle ammunition bench. Built around RCBS's proven seating die design, this tool delivers the consistency competitive shooters and serious handloaders demand. Whether you're developing loads for long-range competition or fine-tuning ammunition for accuracy testing, a quality seating die is essential to controlling bullet seating depth and runout—two critical factors that separate match-grade ammo from the rest.
The MatchMaster line bridges features from RCBS's Gold Medal and Competition series, giving you access to proven technology at a competitive price point. Seating dies are the workhorse of any reloading setup; they handle the precise, repetitive task of inserting and setting bullets to exact specifications. For .22 CM shooters, having a dedicated die ensures you're not swapping or adjusting between different cartridge sizes, maintaining consistency and saving setup time on the press.
If you're already running RCBS equipment or considering building out a complete .22 CM handloading system, this seating die pairs with standard RCBS press equipment and follows the industry-standard 7/8"-14 TPI threading. Handloaders value reliability and repeatability above all else, and RCBS has built its reputation on both. A dedicated seating die for your specific caliber is a smart investment in ammunition quality.

The RCBS MatchMaster Seating Die uses standard 7/8"-14 TPI threading, compatible with any RCBS single-stage press or compatible equipment using industry-standard die mounting.
While the MatchMaster line draws from RCBS's Competition series heritage, this seating die is suitable for any .22 CM handloading application where precision bullet seating is required—whether you're loading for hunting, range work, or competition.
The seating die handles bullet insertion and seating depth only. Most reloaders run a separate sizing die as the first step to resize the cartridge case before seating a new bullet.
