The rim cartridge 8 × 50 mm R (also 8 mm Mannlicher , 8 mm Österreichische Ordonnanz or 8 × 50 Steyr-Mannlicher ) was an Austrian orderly cartridge of the late 19th century.
history
The cartridge was developed after France introduced the 8 × 50 mm R Lebel, the first military cartridge with a low-smoke propellant charge . The black powder cartridge 8 × 52 mm R was used as the starting sleeve and introduced as the M90 with a semi-fuming powder 1890. In 1893 the completely low-smoke powder was available and the cartridges loaded with this powder were designated as M93.
commitment
The 8 × 50 mm R was used in all variants of the Mannlicher M1890 and M1895 rifles as well as in the Schwarzlose machine guns .
Further development
After the emergence of aerodynamically shaped pointed bullets, the 8 × 50 mm R was also given a pointed bullet. This pointed bullet was shorter than the old round head bullet, which is why the case had to be lengthened to 56 mm. Since the floor of the bullet was no longer compressed into the trains due to its aerodynamic shape, the bullet diameter also had to be increased to 8.35 mm. This new 8 × 56 mm R cartridge was introduced as the M30 in 1930.
