The 8x57 is there alright, you just know know enough about armament to see it, since it is not expressed directly as such, as it's listed as "7.92 x 57", having a bullet diameter of 7.92 mm, which equals .323 of an inch.

The I is .318, the IS is .323

Just admit it. You don't have any hands-on experience with the things you are talking about. I, on the other hand, do.

Your mixing up bullet sizes could be dangerous.

I give up. You haven’t a clue.

No. The 7.92x57IS has a bullet diameter of 8.20mm, NOT 7.92mm.
