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

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

Another important advantage lies in the fact that using Bushings puts much less stress on the material and greatly helps to extend the lifespan and use of the shell 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 strict tolerances and polished to offer the best possible finish. Adjustment via the large lock nut provides oversized letters and hash marks that make it precise to turn and easy to read. It adjusts by one thousandth of an inch, and that is exactly what you will get.

The Seater MatchMaster also features our exclusive loading window which 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 mouth of a shell case or put your fingers at risk. The internal sleeve captures and holds the bullet in perfect alignment with the shell and guides it during the seating operation for surprisingly concentric results.
