The 6.5×68mm rebated rim bottlenecked centerfire rifle cartridge (also known as the 6.5×68mm RWS, 6.5×68mm Schüler, or the 6.5×68mm Von Hofe Express) and its sister cartridge the 8×68mm S were developed in the 1930s by August Schüler from 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 completely new rifle cartridge (the 6.5×68mm and 8×68mm S have no other cartridge as parent case) was developed by a gunsmith to fit a specific popular and widespread type of rifle.
