RCBS MatchMaster Competition Neck Bushing Set .300 Remington Ultra Magnum / 300 RUM

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

Another important advantage lies in the fact that using Bushings exerts much less force on the material and significantly helps to extend the life and use of the case itself. Each Sizing Die features a titanium carbide nitride expander which has been specially selected to help reduce force and resistance on the expander ball. Each Die is machined with tight tolerances and polished to provide the best possible finish. Adjustment via the large lock nut offers a scale with oversized letters and hash marks making it precise to turn and easy to read. It adjusts in one thousandth of an inch increments, and that is exactly what you get.

The The Seater MatchMaster also features our exclusive loading window which allows you to drop the bullet through the opening directly into the press - no more balancing the bullet on the mouth of a case or risking your fingers. The inner sleeve captures and holds the bullet in perfect alignment with the case and guides it during seating for surprisingly concentric results.
