As I said this is the "Generic" way to set up an FL die. It is also the recommended set-up by RCBS and others. If you disagree you can take it up with them.
From RCBS instructions.
STEP 5 - INSTALL THE SIZER DIE
Thread the sizer die into the press until the die touches the shell holder when the ram is at the top of the press stroke. Raise the press handle and turn the die down another one-eigth to one-quarter of a turn and set the large lock ring. If you're using a carbide sizer die, make slight contact with the bottom of the die and the shell holder.
1) Install the appropriate Shellholder into the Ram of your Press.
2) Raise the Ram so that it is in its uppermost position.
3) Screw the Full Length Resizing Die/Body Die down into the press until it firmly contacts the Shellholder.
4) Back the Ram away from the Die.
5) Screw the Die down FURTHER into your press an additional 1/8th to ¼ turn.
Note that you will feel the Ram/Shellholder contact the resizing Die before the stroke is completed. Completing the Ram Stroke will fell as though you are snapping the latch on a toolbox.
CASE SIZING PROCEDURE
1. Install the Die into any standard 7/8-14 thread reloading
press or Forster’s Co-Ax® Reloading Press so that it

2. Turn the Die another 1/8 to ¼ turn against the shell holder to
remove all play from the linkage system of the press.
3. Tighten the Cross Bolt Die Lock Ring (DIE-G-10) by using a
7/64 short arm hex key on the Die Lock Ring Screw
