"Pull through reamer? The pull through reamer is a done deal, it is advertised as nothing can go wrong, when using the pull through reamer the chamber is reamed/finished when the bolt closes"

Correct, when the bolt closes the chamber is done. I do not shoot gages, I shoot loaded ammo, because my presses and my dies have threads I can adjust the length of my cases from the shoulder of the case to the head of the case. My cases have a case that off sets head space. to determine head space I measure the length of the chamber from the shoulder/datum to the bolt face. My cases do not have head space, my cases have a length, the length of my case is measured from the datum to the head of the case.

Then there are other bolts, to determine 'other bolts' and their uses would require an Internet search..
