variation is one thing, but there are a number of measurements that are substantially different.
the surest way to figure it out though, would be to take chamber casts of the various firearms for which these cartridges were chambered.
it has always been my understanding that the German round will go into any Soviet gun, but the opposite is often not true.
I would also think that if they were the same cartridge early editions of cartridges of the world, edited by Frank Barnes, would so indicate, but they do not. they list them as two separate, distinct cartridges.
I will have to look again and see how my early COTW handles the .380-200.
