Factory Crimp Die Adjustment

The amount of crimp applied will be consistent if your press has mechanical stops built into the lever linkage, and you lower the lever to the stop every time. Start with the Factory Crimp die turned into the press until it stops against the shell holder with the ram raised all the way. Lower the ram, and turn the die in one full turn. Now try crimping a case, making sure that you raise the ram (lower the lever) all the way to the stop. You will feel slight resistance at the top of the stroke, as the crimp collet is forced up into the die body.

If the crimp is not firm enough, turn the die in another 1/4 turn and try again. If you turn the die in to the point where the four slits in the collet are closed when the ram is raised all the way, you have reached the limit.
