Re: 9mm Borchardt?
Hi Bill,
Alas, not much is known :-(
Hugo Borchardt spent a number of years attempting to improve his C93 into a pistol acceptable to some national army, and finally gave up circa 1911. The reference to the â??9 mm Borchardtâ?? cartridge is based on speculation that one of his improvements was to a long 9 mm cartridge (similar to the 9x25 mm Mauser Export cartridge). But all this is highly speculative.
There is another line of speculation concerning the â??9 mm Borchardtâ?? cartridge that seeks to link this cartridge to DWMâ??s attempt to interest the British military in the Luger. The British cartridge requirements were very similar to the US cartridge requirements, and Herr Luger is known to have attempted to create a Luger chambered for a 9 mm cartridge that approximated the British muzzle energy requirements (without meeting the requirement for a .45 caliber bullet) by creating a longer (and probably slightly necked) 9mm cartridge with a high muzzle velocity.
And there is still another line of speculation that wants to link the â??9 mm Borchardtâ?? cartridge to a variation of the 1910 Bergman (which was chambered for the 9x23 Bergmann/Bayard) and would have been less hard to convert to take a cartridge of the length of the â??9mm Borchardtâ?? than would the Luger.
This is yet another of those areas were we have tantalizing hints concerning events, but the project (whatever it may have been!) was a commercial failure and so little to no primary source information is available. While the project was ultimately a failure, it lasted long enough to produce some significant amount of ammunition, as a number of â??9 mm Borchardtâ?? cartridges survive today. Fertile ground for hours of entertaining conversation
Best regards,
Kyrie
