"the gage you suggested was for measuring the distance from the head to the shoulders, right? so after the 1st fire, you measure that distance, and annotate it. that's your fired shoulder size. after the 1st fire, that's where you want to resize the casing to. is this correct?"

Now you've got it. Again, it matters not what the case datam/diameter line is nor where it's measured nor if it's rimmed or belted, size them all as rimless and make them fit your chamber.

IF you measure and duplicate the fired shoulder location in your longest fired case (they WILL vary a couple thou, nothing you can do about that) then you won't get a "crush fit", you will have the same fit as after it was fired and that's plenty loose. (They will also vary a couple thou after being sized, so use the longer ones as your reference for adjusting the sizer.)
