Set your sizing die so when you bring up you case to the die the
handle has a slight cam lock to it, this way the case is full length sized.
you can adjust your sizing die a little at a time so not to over adjust
the handle to the die.
My procedure for setting a sizing die:
(1)Bring the ram to it's highest point, full stroke, operating lever all the way down. (2)Now, screw the seating die in until it is tight against the shell holder. (3)Next, run a fired case into the die and with operating lever/ram in position (1) check to see if there is any day light between the mouth of the die and the shell holder. (4)Readjust sizing die until there is zero clearance between the mouth of the die and the shell holder with a fired case in the shell holder. (5)Set locking ring.
What you are doing here is adjusting the sizing die to account for all of the play in the linkage of your press. As Nomad said, you'll feel the operating lever "cam over" when you reach that magic point, my procedure just provides you with a visual reference to help you get there. This adjustment is imperative with straight walled cartridges because if you don't it can translate to a very subtle bulge near the base of the case which will lead to loaded rounds that need "some encouragement" to fully seat in the cylinder of your pistol. Good luck and welcome to your new addiction.
