You didn't translate it to a like Brit/American caliber. That's what I was going for.

Perhaps you could post an analogous English system caliber in a common round.

Interesting to know about the 8mm. Were they ammunition left over from WWI?

303 British (7.7x56Rmm) and 8mm Mauser (7.92x57mm) were both adopted in 1888, for the Lee rifle and the Modell 1888 Kommissionsgewehr (Commission Rifle) of Britain and Imperial Germany, respectively.

The Brits used various modifications of the Lee system chambering 303 until 1957. The Germans adopted the Mauser system in 1898 and used modifications chambering 7.92x57mm until 1945. Both nations used various models of machine gun in their respective rifle chamberings during the same periods.

The 7.92 Kurz was new manufacture at the time, but the 8mm Mauser round predated WW1. However, it too continued to be manufactured during WW2.

Of course, that’s not that unusual. At this point the Russian 7.62x54R round has been in mainline top tier military service over 120 years and it doesn’t look to be going away any time soon.
