RCBS MatchMaster Competition 338 Lapua Magnum Bushing Neck Sizing, Micrometer Bullet Seating 2 Die Set

Overview

The RCBS MatchMaster Competition Die Set in .338 Lapua Magnum is built for precision handloaders seeking maximum accuracy, minimum runout, and consistent case concentricity. Crafted from case-hardened steel with precision-drilled, reamed, and hand-polished interior surfaces, these dies offer exceptional fit, finish, and durability. The neck-sizing die utilizes precision-machined, interchangeable neck bushings (sold separately) to allow exact control over neck tension while minimizing brass work to extend case life. It also includes a Titanium Carbo Nitride (TiN) expander for smooth case extraction and reduced brass buildup. The matching bullet seating die features a deep blued finish and a large oversized micrometer with clear hash marks for adjustments down to one thousandth of an inch. A free-floating, self-centering seating stem pairs with an exclusive loading window and internal retention sleeve to securely catch, hold, and guide the bullet in perfect alignment with the case mouth, preventing smashed fingers and delivering astoundingly concentric results.
