792×57mm

The 7.92×57mm Mauser cartridge, also known as 8mm Mauser, is a rimless rifle cartridge developed by the German Empire in 1888. It was designed to replace the older 8x57I cartridge. The 7.92×57mm Mauser quickly became one of the most popular and widely used military cartridges of the 20th century. It was adopted by Germany as its standard infantry rifle cartridge and saw extensive service in both World War I and World War II.

The cartridge's design featured a tapered case and a spitzer (pointed) bullet, which offered good ballistic performance for its time, providing a flat trajectory and significant stopping power. Over its service life, various bullet weights and velocities were developed for different applications, including standard ball, tracer, armor-piercing, and soft-point ammunition. The 7.92×57mm Mauser was chambered in a variety of iconic firearms, most notably the Mauser Gewehr 98 and Karabiner 98k rifles, as well as the MG 34 and MG 42 machine guns.

Beyond Germany, the 7.92×57mm Mauser was adopted or manufactured by numerous other countries, including Austria, Czechoslovakia, Poland, and Turkey, often for their own domestically produced rifles and machine guns based on Mauser designs. Its widespread military use meant that it was also produced in large quantities and saw considerable civilian use for hunting and sport shooting, particularly in Europe and North America, even after its military obsolescence. While largely replaced by intermediate cartridges like the 7.62×39mm and 5.56×45mm NATO in military contexts, the 7.92×57mm Mauser remains a historically significant and still relevant cartridge.
