That's what a "go gauge" is- zero headspace, according to SAAMI specs.

My bolt closed easily on all five pieces of FL sized brass I tried. Why do you feel "zero" headspace is an issue, when I'm only going to use brass that comes out of the die I set it with?

I would agree if I planned to use factory ammo- but that's not the case.
