With 7/8-14 dies and bottle neck rifle cases, "camming over" ensures the case is forced into the die for proper head space.

The Star is designed for Pistol cases and, as such, camming over is not needed nor desired.

If the face of the Carbide sizing die contacts the shell plate and you "cam it over" you risk fracturing the Carbide ring.

To adjust the Carbide Sizing die, back it off and cycle the press down where it is at "bottom dead center". Hold the handle with one hand and screw the die down until it just touches the shell plate. Nip the lock nut to hold the die in position and cycle the press fully to ensure that the die is not being forced into the shell plate.
