The cases are loaded by the firm of Hannes Kepplinger using 6,5g (100grs) or 8,4g (130grs) Hornady bullets and modern double-base powders. The ballistic information is impressive, the energy is better than of a 30-06. The hunting success in not only limited to European game. The cartridge fits well for African game too.
Generally thought to have been introduced 1987 (Meyer says 1989) which is believed to correspond with the MEN "V" date code. About 1990, Dynamit Nobel (RWS) responded to these developments by issuing a quite similar cartridge known as the 6,5 x 65 RWS (W57). It may been assumed that Dynamit Nobel
