RCBS 11140 MatchMaster Competition Seating Die .223 Rem

The RCBS 11140 MatchMaster Competition Seating Die is a precision reloading die engineered for serious match and competition handloaders working with the .223 Remington cartridge. Built around RCBS's proven MatchMaster platform, this die features a micrometer-adjustable seater for repeatable, fine-tunable bullet seating depth with no shims or spacers required, paired with a free-floating, self-centering bullet seating system that holds the bullet concentric with the case mouth for straight, consistent seating shot after shot.

A built-in bullet loading window with bullet retaining system lets the reloader drop a match bullet into place by hand, keeping fingers clear of the press ram and protecting the delicate ogive during the seating stroke, a real benefit when seating high-end competition projectiles.

Cut to the industry-standard 7/8x14 thread pattern, the MatchMaster seats cleanly on virtually any single-stage or progressive reloading press. Like all RCBS reloading tools, this die is precision-machined in the USA to the standards match shooters and handloaders have trusted for decades.

Designed as a seating die only, the MatchMaster is intended to pair with your existing full-length sizing die and is a direct upgrade for handloaders chasing tighter groups, more consistent velocity, and match-grade accuracy from their .223 Remington reloads.
