RCBS MatchMaster Competition Bushing Full Length Dies Set .300 Remington Ultra Magnum

The Bushing Die allows the use of interchangeable bushings specific to diameter, enabling perfect formation 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 greatly helps to extend the life and usability of the case itself. Each Sizing Die features a titanium carbide nitride expander that has been specially chosen to help reduce force and resistance on the expander ball. Each Die is machined with strict tolerances and polished to offer the best possible finish. Adjustment via the large lock nut provides 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’s exactly what you get.

The Seater MatchMaster also features our exclusive loading window which allows you to drop the bullet from the opening directly into the press — no more trying to balance the bullet on the case mouth or risking your fingers. The inner sleeve captures and holds the bullet in perfect alignment with the case and guides it during the seating operation for astonishingly concentric results.
