Bullet Seating Die Adjustment

The trick is to set the bullet seating depth first, then the crimp. This is done as follows; With an empty, sized case in the shell holder, hold the ram at the top of its stroke. Turn the bullet seating die body down over the case until you feel it come to a stop. This will be when the case mouth contacts the crimp shoulder inside the die. Mark this position by turning the lock ring down against the turret or press frame. Now adjust your bullet seating depth. Once you have the bullet seated to the desired depth, back the bullet seater adjuster out about 1 turn. Now turn the bullet seating die body in to apply the desired crimp. Once this is established, hold the ram at the top of its stroke and spin the bullet seater adjuster down until it stops.

It is a good idea to carry this out with an empty case, so that after you have seated the bullet, you have a perfectly safe “dummy” cartridge (or gauge) to repetitively set seating depth and crimp on future occasions.

Once you have this “dummy” gauge, all you have to do is place it in the shell holder, raise the ram to the top of its stroke, turn the bullet seating body down until it stops, and then turn the bullet seating depth adjuster in until it stops. Since the crimp and the seating depth were already set, the die will return to very close to the same settings.
