     This round was based on the 7.62x25mm Borchardt round from 1893. Developed by Georg Luger, this round was made shorted and was intended to be loaded to a much higher chamber pressure than the relatively weak Borchardt round. The earliest Luger pistols were chambered for it. The round is particularly significant as it led directly to the extremely successful 9x19mm round.
