RCBS 15504 MatchMaster Duo 2-Die Set .308 Winchester - Full-Length Sizing & Seater Dies

The RCBS MatchMaster Duo is a precision 2-die reloading set engineered for .308 Winchester bottleneck rifle cases. It pairs a full-length sizing die with a micrometer-adjustable seating die for consistent, match-grade reloads. The MatchMaster design does not require separate bushings, so handloaders can seat different bullet profiles cleanly in the same die.

The micrometer seating die allows repeatable incremental seating-depth adjustments, while the full-length sizing die resizes the case body and neck to factory or semi-dimensions for reliable chambering. The set is factory tuned for .308 Winchester (7.62x51mm NATO) and is a natural fit for bolt-action precision rifles and hunting rifles chambered in .308 Win. The MatchMaster Duo is part of RCBS's full-length die family and is backed by a limited lifetime warranty.
