RCBS MatchMaster Duo Features The RCBS MatchMaster Duo brings together two purpose-built dies for the 6mm Creedmoor handloader who wants repeatable precision without extra complexity. The full length sizing die resizes spent brass back to factory dimensions on every pass which means cases chamber reliably whether they started as new brass or mixed once-fired cases. No bushings are required so there is no need to stock a separate bushing set or second-guess neck tension setup before loading a batch. This full length approach has been trusted by generations of reloaders because it delivers consistent results without extra fuss at the bench. The MatchMaster seating die is the half of the set built for the fine adjustments that matter most to accuracy featuring a micrometer adjustable dial for repeatable seating depth across every round. That repeatability means a shooter can return to a proven seating depth setting between range sessions without re-zeroing the die each time. Together the two dies form a complete two-die set in one box saving the step of sourcing a sizing die and seating die separately. Backed by a limited lifetime warranty and made in the USA the RCBS MatchMaster Duo is built for handloaders chasing match-grade consistency from their 6mm Creedmoor rifle.
