RCBS MatchMaster Competition Bushing Full Length Dies Set .300 Winchester Magnum #15308

The Bushing Die allows the use of interchangeable bushings specific for diameter, enabling perfect formation of the case neck collar. 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 the Bushing exerts much less force on the material and significantly helps to prolong the life and use of the case itself. Each Sizing Die features a titanium carbide nitride expander that has been specially selected to help reduce the force and resistance on the expander ball. Each Die is manufactured with strict tolerances and polished to offer the best possible finish. The adjustment through the large lock nut provides an adjustment with oversized letters and hash marks that make it precise to turn and easy to read. It adjusts in thousandths of an inch, and that is exactly what you will get.

The Seater MatchMaster also features our exclusive loading window that allows you to drop the bullet from the opening directly into the press – no more balancing the bullet on the case mouth or risking putting your fingers in danger. The internal sleeve captures and holds the bullet in perfect alignment with the case and guides it during the seating operation for surprisingly concentric results.
