Can you measure the headspacr on a fired case and compare it to the same measurement on the cases that did not fire?

I had a CCI Primer misfire a while back and posted about it ( link below )

Jaco was one of the respondents who correctly diagnosed the cause. A simple adjustment of my FL Die resolved the matter.
I think CCI Primers have harder metal in the cups than other brands which makes correct headspacing all the more essential for reliable ignition.
