Weil ich gestern hier bei der Forumssuche auf genau die diese, nicht ganz richtigen, Antworten gestossen bin, hier ein Beitrag für zukünftige Suchende:
Ja:
Ist das selbe.
Die Unterschiede im Pulverdruck stammen aus unterschiedlichen Messmethoden. .308 ist nicht per se stärker.

Not everything you read online is true, and, unfortunately, it is very easy to come by stupid ideas in printed version, which should, at least, be a result of responsible individuals, but it is also true that just because something’s been said many times it doesn’t mean it’s true: Vox Populi, sure- but not Vox Dei.
So to sum up: it is true that the military ammunitions have a maximum limit of 50 000 units of pressure but it is expressed in CUP while the civilian ones get to 62 000 PSI and CUP and PSI cannot be confused!
The infamous difference of 12 000 PSI is due to the wrong calculation and it makes no sense because you cannot subtract values expressed in different measuring units.
gut informierte werden jetzt die augen rollen, ändert nix daran dass man in 8 von 10 suchresultaten noch immer die prominente antwort bekommt dass es sicher ist in einer .308 eine 7,62 zu verschiessen, andersrum aber nicht.The one thing that actually matters is a different quota of larger cartridge chambers present in military guns: if we think that military ammunition has a more compact bullets when it comes to the type and width of the brass, while the civilian models have thinner cases so it can be completely loaded. This is why, if you use the civilian bullets in your military cartridge chamber, you could cause excessive lengthening of the case.
So what’s the risk? Basically, there is none, if you use a factory-manufactured cartridge: excluding the extreme situations, the case gets longer and thinner near the case head, but there is no separation or breakage. However, if you use the same cases to reload your cartridges, obviously the breakage of the cases is going to be noticeable from the first loading.
