What is 30 caliber luger?

The 30 caliber Luger, also known as 7.65x21mm Parabellum, is a pistol cartridge designed by German firearms manufacturer Georg Luger in the early 20th century. It was originally developed to be used in the Luger semi-automatic pistol, which was used extensively by the German military during World War I and World War II.

The 30 caliber Luger cartridge uses a 7.65mm bullet with a weight of around 93-98 grains. It typically has a muzzle velocity of around 1,100-1,200 feet per second and a muzzle energy of around 300-350 foot-pounds.

While the 30 caliber Luger was widely used by the German military during the World Wars, it has since fallen out of favor and is not commonly used today. However, it is still occasionally used for target shooting and in some hunting applications.
