I couldn’t find anything on case headspace, dead space or real headspace in SAAMI’s glossary but I did find this and believe that this is what your referring to -
From SAAMI -

HEAD CLEARANCE
The distance between the head of a fully seated cartridge or shell and the face of the breech bolt when the action is in the closed position. Commonly confused with headspace.
Bullet,
You won't find any reference to case headspace or some of the other terms that we are using here because, SAAMI doesn't deal with anything other than factory ammo in SAAMI spec chambers. Reloaders use the term and understand (for the most part) what is being said. And, No, head clearance is not being discussed here.
