What??

I'd beg to differ with you. SCATP specifies very exactly how chamber pressures are measured, among other things.

It sounds as though you do not understand "standards" at all. A standard specifies exactly how something is to be done and exactly what equipment is to be used. Standards may change over the years and specify different equipment and numerical values (such as pressure, for one), but that's why they put dates on them.


All SCATP states about chamber pressures are that SAAMI guidelines will be followed by the military.

Meaning the .223 and 5.56 are both loaded to the same chamber pressures. The only differences being the throat of the two chambers.
