RCBS MatchMaster Competition Seat Die 300 PRC

The RCBS MatchMaster Competition Seat Die is a precision bullet seating die purpose-built for the 300 PRC cartridge, designed for competitive shooters and precision reloaders who demand exact, repeatable bullet seating depth.

This seater die features a bullet seating window with bullet retention system that holds the projectile in place during seating to prevent tip deformation and ensure consistent alignment down the bore. The oversized micrometer adjustment lets reloaders dial seating depth to precise thousandths of an inch, while the free-floating, self-centering seating stem centers the bullet in the case neck for concentric, straight-line seating.

Sold as a dedicated seater die only (no sizing or decapping function included), the MatchMaster pairs with a compatible full-length sizing die to form a complete precision reloading setup for the 300 PRC. Whether loading for long-range competition, big-game hunting, or match shooting, this die delivers the consistency serious handloaders expect from RCBS.
