The proof pressure requirements between the .308 and 7.62 NATO are the same, does someone have the wrong information……….AGAIN

There is LESS than 2,000 psi difference between the two rounds

Military 7.62 50,000 cup (proof pressure 67,500) Note: Some 7.62 military is 52,000 cup
Civilian .308 52,000 cup (proof pressure 67,600)

In the attached photos below the pressures are listed as “PSI” BUT they are in copper units pressure pounds per square inch, ALL military manuals are listed as PSI back to the time when Christ was a Corporal (CUP-PSI and NOT transducer PSI)

NOTE: You can shoot .308 and 7.62 interchangeably, they will NOT damage a 2A1 or 7.62 No.4, there is less the 2,000 PSI difference, which is the same difference between military 30-06 ammunition and commercial 30-06 ammunition and we never complained or damaged shooting commercial 30-06 ammunition in our Springfield 03s.
