RCBS MatchMaster Competition 30-06 Springfield Bushing Neck Sizing, Micrometer Bullet Seating 2 Die Set

Overview

The RCBS MatchMaster Competition 30-06 Springfield 2-die set is designed for precision handloaders seeking exact case dimensions and minimal bullet runout. Crafted from case-hardened steel with precision-drilled, reamed, and hand-polished internal surfaces, the set includes a neck sizing die and a micrometer-adjustable seating die compatible with standard 7/8"-14 presses. The sizing die utilizes interchangeable neck bushings to control neck tension and minimize brass stretching, paired with a titanium nitride-coated expander for smooth extraction and reduced buildup. The seating die features a free-floating, self-centering seating stem with an oversized micrometer dial for thousandth-of-an-inch adjustments, alongside an exclusive loading window and internal retention sleeve that safely aligns and holds the bullet during seating.
