 The 8×68mm S case has functioned as the parent case for the .375 Hölderlin (9.5×68mm), which is essentially a 9.53 mm (.375 caliber) necked-up version of the 8×68mm S. The wildcat status of the .375 Hölderlin ended in 2007 when it got C.I.P.certified and became an officially registered and sanctioned under the 375 Hölderlin designation member of the German 68 mm "family" of magnum rifle cartridges.If the .375 Hölderlin will become available as factory ammunition, like the older cartridge "family" members (8×68mm S and 6.5×68mm), is still unknown.
