Headspace is not brass body

Headspace is not the body of the case, correct. Headspace is the distance from the bolt face to a certain point in the chamber. When you fire the case, it blows the shoulder forward to fill any empty headspace clearances between the brass and the chamber.
But it doesnt only grow in the one direction, it also grows out round and gets fatter which is often what you feel in the bolt resistance when chambering and extracting.
Full Length sizing die sizes down the base diameter, shoulder diameter, shoulder set back and neck diameter.
Body die sizes down the base diameter, shoulder diameter, shoulder set back
Neck die sizes down the neck
How deep you screw in the body or full length die into the press controls how much it sets the shoulder back, the deeper you screw it down, the shorter the space allowed for the shoulder to exist before it gets pushed back.
How the shoulder reacts depends. If its been several times fired and has gotten progressively work hardened, you may find that it springs back variable amounts. If you have nice new or freshly annealed cases then the shoulder should pretty much stay where you size it to.
If you find that the shoulder datum dimension gets longer, your die isnt screwed down far enough and its the squeezing of the body diameters thats shoving the shoulder forward until the die gets lowered enough to rebend where the shoulder is.
In short:
Your die diameters are pretty much what they are as set by the die and eventually need to be squeezed down after firing.
How far you screw the die itself in controls how much headspace clearance you make between the case shoulder and the chamber shoulder.
