Quote:
head space is the length of the chamber
I disagree.
Wogpotter, I do not trust you, I question your motives.
What purpose are you serving when you omit:
"from the datum to the bolt face".
Head space is the length of the chamber from the datum/shoulder to the bolt face.
Before the Internet, any one that purchased a catalog from Santa Fe Arms received, in the catalog, a glossary of terms, my catalogs from Santa Fe Arms were published in the mid 50s. Back then a case did not have head space. Included in the glossary of terms covering head space they included head space as it applied to the belt and rim.
