RCBS MatchMaster Competition 6mm BR (Bench Rest) Bushing Neck Sizing, Micrometer Bullet Seating 2 Die Set

Overview

The RCBS MatchMaster Competition 2-die set for 6mm BR (Bench Rest) is designed to provide maximum precision for competitive handloaders. The set includes a neck sizing die that utilizes interchangeable neck bushings to achieve exact neck tension without resizing the case body, and the MatchMaster Competition seating die. The seating die features a unique bullet-seating window and a bullet-retaining system, which eliminates manual bullet alignment and simplifies the seating process. The MatchMaster seating die also incorporates a micrometer-adjustable, free-floating, self-centering seating stem for precise depth control. For optimal performance, the sizing die requires RCBS neck bushings (sold separately), sized to 0.002 to 0.003 inches smaller than the neck diameter of a loaded cartridge. This set is engineered to reduce runout and improve cartridge uniformity for benchrest and F-Class shooting.
