RCBS MatchMaster Duo 300 PRC 2-Die Full Length Set

The RCBS MatchMaster Duo two-die set pairs RCBS's standard full-length sizing die with the premium MatchMaster micrometer-adjustable seating die, calibrated specifically for the 300 PRC precision rifle cartridge. The MatchMaster seating die offers precise, repeatable bullet seating depth via its fine micrometer adjustment, while the full-length sizing die resizes fired cases back to spec and handles decapping in a single step, with no bushings required. Together, they deliver reliable, match-grade reloads for long-range shooters running the high-performance 300 PRC.

The set is built around a standard 7/8"-14 thread pattern and uses shellholder #38 (sold separately). Like every RCBS die, the MatchMaster Duo carries a Limited Lifetime Warranty and is proudly made in the USA. The MatchMaster Duo line is also offered across a wide range of bottleneck rifle cartridges from .22 ARC up to .338 Lapua, allowing reloaders to standardize on a single die system across their precision rifle battery.
