 This Treaty prohibited the use of standard military weapons and ammunition by Germany.However, civilian hunters didn't want to give up on this great round, so a new cartridge was designed by the German arms manufacturer Deutsche Waffen und Munitionsfabriken (DWM).Extending the 7.92×57mm Mauser cartridge case by 3 mm (2 mm of lengthened body plus 1 mm of lengthened neck) created the 8×60mm S. The 8×60mm S bullet diameter is 8.22 mm (.323 in) as found in the 8×57mm IS.
