The RCBS MatchMaster Duo Set for 338 Lapua (brand part no. 16604) pairs RCBS‘s premium MatchMaster seating die with a rugged Full-Length sizing die in one caliber-specific package. The seating die adjusts with a micrometer for repeatable seating depth, and neither die requires bushings, so the set is ready to load straight out of the box. Handloaders running 338 Lapua for competition or long-range work get elite-level consistency without piecing together a set from separate purchases. RCBS backs the set with a Limited Lifetime Warranty and builds it in the USA.
