RCBS MatchMaster Duo 2-Die Set .338 Lapua Magnum

The RCBS MatchMaster Duo 2-die set is purpose-built for precision reloaders working with the .338 Lapua Magnum, one of the most demanding long-range bottleneck rifle cartridges on the market. This factory-matched duo pairs a full-length sizing die with a MatchMaster seating die to deliver consistent case preparation and exact bullet seating for match-grade ammunition.

The full-length sizing die resizes the case body back to SAAMI specification and handles the tough bottleneck geometry of the .338 Lapua Mag case, while the MatchMaster seating die features RCBS's floating-seat design that requires no bushings for repeatable, precise seating depth. Together, the two dies cover every step needed to turn fresh brass into loaded, ready-to-fire precision rounds.

Covering the most popular precision rifle cartridges from .22 ARC up to .338 Lapua, the MatchMaster Duo series is backed by RCBS's limited lifetime warranty and proudly manufactured in the USA. This 2-die set is an ideal choice for long-range competitive shooters and serious .338 Lapua Magnum handloaders who demand accuracy and consistency from their reloading setup.
