RCBS MatchMaster Competition Seater Die .300 Winchester 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 will no longer have to try to balance the bullet on the mouth of a case or put your fingers at risk. The inner sleeve captures and holds the bullet in perfect alignment with the case and guides it during the seating operation for remarkably concentric results.
