RCBS MatchMaster Competition Neck Bushing Die Set Features The RCBS MatchMaster Competition Neck Bushing Die Set uses a changeable neck bushing system that has been trusted by benchrest and long-range precision shooters for years allowing handloaders to precisely set neck tension for their particular rifle and bullet combination. Each die is made from case hardened steel with inside surfaces precision-drilled reamed and hand polished to exacting standards. The titanium nitride coated expander reduces brass build up and delivers silky-smooth case extraction both of which help minimize stretch on the case neck across repeated firings. This attention to consistency is exactly what competitive .308 Win shooters need to extend brass life and maintain tight groups. The MatchMaster Competition Seating Die sets this system apart with its bullet seating window and bullet retaining system letting handloaders simply place the bullet in the window and raise the case into the die to seat it without smashed fingers or misaligned bullets. A micrometer adjustable free-floating self-centering bullet seating stem delivers the easiest most accurate bullet seating available on the market. The large oversized adjustment knob features bold letters and hash marks for precise repeatable one-thousandth of an inch adjustments. This RCBS MatchMaster set gives precision handloaders a complete solution for crafting match-grade .308 Win ammunition available for sale at GrabAGun.
