Magnum H Press Priming Arm

The No. 407 H-Ram will allow you to use current snap-in shell holders in the Magnum 'H' press, but the original primer arm is too large in diameter to go through the center hole of the shell holder. This primer arm will work with all current snap-in shell holders. It includes both large and small primer punches and cups, and replacement parts are available if you should ever need them.
