Fired cases are shorter because the case has expanded & the case walls are bowed out.

Once you size them, & straighten the case walls out, the change in the measured length is proportionally longer to the difference which varies with the load's pressure & the chamber it was fired in.

Size the cases first, then trim them.

If needed, reduce the diameter of your trimmer's pilot to fit the sized case.
