8×68mm S

8×68mm S

The 8x68mm S rimless bottlenecked rifle cartridge (the S means it is intended for 8.2 mm (.323 in) groove diameter bullets) and its necked down sister cartridge the 6.5x68mm (no S, or anything else, required) were developed in the 1930s by Mr. Schüler of the August Schüler Waffenfabrik, Suhl, Germany as magnum hunting cartridges that would just fit and function in standard sized Mauser 98 bolt action rifles. This is one of the early examples where a de novo rifle cartridge (the 8x68mm S and 6.5x68mm have no other cartridge as parent case) was developed by a gunsmith to fit a specific popular and widespread type of rifle.
