RCBS MatchMaster Competition 300 PRC Bushing Full Length Sizing, Micrometer Bullet Seating 2 Die Set

Overview

The RCBS MatchMaster Competition Die Set for .300 PRC is engineered to give precision handloaders ultimate control over neck tension, concentricity, and round consistency. The full-length sizing die utilizes precision-machined neck bushings (sold separately) to allow fine-tuning of neck sizing to exacting tolerances, separating neck sizing from body sizing to protect case shoulders and maintain proper headspace. It features a titanium nitride-coated expander that ensures silky-smooth case extraction, reduces brass build-up, and minimizes case neck stretch. Rounding out the set is the MatchMaster Competition Seating Die, which features a convenient bullet seating window and retaining system to eliminate misaligned bullets and pinched fingers. Combined with a micrometer-adjustable, free-floating, self-centering bullet seating stem, this die set delivers reliable, match-grade performance for long-range shooting and high-volume competitive preparation. To determine the correct neck bushing size, handloaders should measure the outside neck diameter of a loaded cartridge and subtract .002" to .003" to accommodate brass spring-back.
