The 8×68mm S rebated rim bottlenecked centerfire rifle cartridge was developed in the 1930s by August Schüler of the August Schüler Waffenfabrik, Suhl, Germany as a magnum hunting cartridge that would just fit and function in standard-sized Mauser 98 bolt-action rifles. The bore has the same lands and grooves diameters as the German 7.92×57mm Mauser service cartridge (designated as "S-bore").

Schuler’s 8x68 S can to a great extent be compared to the .300 Winchester Magnum. The 8x68s case has a base diameter of .523” (13.3mm) and a slightly rebated rim at .511” (13mm).

The 8x68S has a rebated rim, since the body diameter just forward of the extractor groove measures a fat .524 inch. The shoulder angle is just over 14.5 degrees. The maximum cartridge overall length is 3.38 inches, so the heaviest 8mm bullets are seated pretty deep in the case.
