This die is the perfect die to have in a progressive reloading press after the powder drop station to automatically check dropped charges. Even though it resembles a standard reloading die, the powder cop die has a moveable stem in the middle that whe properly set will move up to display a white o-ring that will be even with the surface of the die when the correct powder charge is in the case. If there is no powder charge in the case the stem will not rise. If there is an overcharge of powder, the stem will lift the O-ring well above the surface of the powder cop die.
