RCBS MatchMaster Competition Seater Die .300 Norma Magnum

The Seater MatchMaster also features our exclusive loading window that allows you to drop the bullet through the opening directly into the press – you’ll never have to try balancing the bullet on the case mouth or risk your fingers again. The internal sleeve captures and holds the bullet in perfect alignment with the case and guides it during the seating operation for remarkably concentric results.
