Ammunition power

[II/JG54_Emil]

This is something I found in the internet quoting Oleg.

Can someone explain (preferably Oleg himself) why there is a huge tendency to over-model allied guns and under-model axis guns? The only exception is the German MG 17 7.92 machine-gun which was mounted in the bombers.(the true bullet velocity is marled blue or red and added by me, I checked different soucres in the internet for one and the same gun)
Was it ever changed to historically correct?

I don´t want to bring up old discussion that probably already took place. But I suppose it´s similar with the flight-model (and I always wonderd why a 109 or a 190 is close to be unflyable with a hole in the wing, in contrast to some allied planes that even fly with some parts of the wing broken off)


I would hate to see the same happening again in SoW.
It should be historically correct.

Or otherwise all fly the same planetype to have a balanced game.
