The 8x57 I thought is still quite popular in Germany? Certainly I remember cheaper sort of customised M98's available in the Frankonia catalogues being available in 8x57.

I think it is a great cartridge on par with the .303, .308, .30-06 and a little bit more unique outside of Central Europe.

The 10.75x68 is a true big bore classic. Had a terrible reputation in its earlier days due to the projectiles being too soft, but with the good well constructed bullets available today, a pretty useful cartridge.
