I use Lee dies with my RL450B.  The instructions state to adjust some of the dies to the point where they just touch the shell plate and then to back off slightly.  To adjust the dies that far down in my Dillon press, there is only a couple of die threads sticking out of the die for the lock nut to screw into.  Thus just doesn't seem right.  Is the head of the Dillon press just so much thicker than some of the other presses out there or am I doing something wrong?
