 Michael W. Mayerl from the Styria Arms company in Austria in 2005 as a reliable beltless high power cartridge for Mauser 98 rifles.The parent case is shortened to 65 mm (2.559 in) case length and necked down to 7.82 mm (.308 in) calibre.The shoulder angle is the same as the 8×68mm S so fire forming is not necessary and no new headspace gages are needed.
