RCBS MatchMaster Competition Neck Bushing Set .300 Winchester Magnum

The Neck Bushing Die allows the use of interchangeable bushings specific to diameter, perfectly forming the case neck. Bench and Long Range shooters use these systems to precisely set the neck tension on the bullet, allowing them to achieve the highest possible accuracy.

Another important advantage is that the use of Bushings greatly reduces material stress and significantly helps to prolong the life and use of the case itself. Each Sizing Die has a titanium carbide nitride expander that has been specially chosen to help reduce the force and resistance on the expander ball. Each Die is machined with tight tolerances and polished to offer the best possible finish. Adjustment through the large large nut provides an adjustment with oversized letters and hash marks that make it precise to turn and easy to read. It adjusts one thousandth of an inch, and that is exactly what you get.

The The Seater MatchMaster also features our exclusive loading window that allows you to drop the bullet from the opening directly into the press – you will no longer have to try balancing the bullet on the case mouth or risk your fingers. The inner sleeve catches and holds the bullet in perfect alignment with the case and guides it during the seating operation for surprisingly concentric results.
