In 1917 Brenneke necked down his 8×64mm S design of 1912 to 7 mm calibre, introduced it as the 7×64mm, and achieved major commercial success. The 7×64mm offered 10-12% more muzzle velocity than the 7×57mm Mauser. This results in a flatter trajectory and better performance at longer range. In the years between World War I and World War II, the 7×64mm was often regarded by German hunters as a "miracle cartridge", and dozens of different factory loads were available on the German market. It was so highly regarded that the Nazi German "Wehrmacht", during the 1930s, even considered replacing the 8×57mm IS in favour of the 7×64mm for their snipers. The "Wehrmacht" decided — just like the German Army had in 1912 — to stay with the 8×57mm IS cartridges for their Mauser Karabiner 98ks to keep logistics as simple as possible.
