The Universal Hold-Down Die is designed for use on Mark 7 and other progressive presses which swage primer pockets. The die is equipped with a sturdy rod which is designed to reach down inside the case and hold the case firmly in position as the swaging operation takes place. This prevents cases from being torn out of the shell plate damaging it and the brass. Two rods are included to cover the full range of rifle and pistol cases. The die body is also made of corrosion resistant stainless steel which protects it from rust and keeps it looking like new for a lifetime of use.
