RCBS MatchMaster Competition Full-Length Bushing Set Features The RCBS MatchMaster Competition Full-Length Bushing Die Set is machined from case hardened steel with internal surfaces precision-drilled reamed and hand polished to exacting standards. This full length sizing die uses interchangeable neck bushings a system favored by benchrest and long range precision shooters for years allowing reloaders to change the self-centering bushing to precisely control the amount of tension placed on the bullet. Working the brass only as much as necessary extends case life significantly compared to standard full length dies. This two die set is built specifically for the 6mm ARC cartridge and threads into a standard 7/8-14 press. The companion seater die in this set is finished with a deep blued finish reminiscent of fine firearms and features a large oversized adjustment knob with bold letters and hash marks for precise easy to read seating depth changes. An exclusive loading window allows the reloader to drop a bullet directly into the die and run the press to seat it eliminating the awkward balancing act common with standard seater dies. An internal sleeve catches and holds the bullet in perfect alignment with the case throughout the seating stroke producing remarkably concentric finished rounds. For 6mm ARC reloaders chasing match-grade consistency the RCBS MatchMaster Competition Bushing Set is available for sale at GrabAGun.
