The Austro-Hungarian 8×50mmR Mannlicher or 8×50mmR M93 is a service cartridge dating back to the days of semi-smokeless powder. It was later replaced by (and many weapons were rechambered for) the 8×56mmR cartridge.^{[citation needed]}

History

M90

In approximately 1890, the

Upon perfection of a completely smokeless powder by the Austro-Hungarians in 1893, the loading was again updated and thus re-designated as the "8mm M.1893 scharfe Patrone". It used the same bullet as the two previous loadings with a 43 gr charge of the new Gewehrpulver M.1892. This improved ballistics slightly, which had been about 200 ft/s (61 m/s) less out of the "repetier-carabiner" Mannlicher M1890 Carbine, to 2,035 ft/s (620 m/s) out of the M.88/90 and later Mannlicher M1895 Rifles.

Current use

The

The 8×50mmR Mannlicher cartridge has a long history of sporting use in India, as it was a simple matter to modify the Lee–Enfield action to accommodate the 8×50mmR in place of the .303 inch cartridge, thus providing a solution to the British colonial administration's 1907 ban on civilians possessing rifles chambered in British military calibres while offering a cartridge of similar capabilities.

British gunmakers BSA produced sporting versions of the Lee–Enfield military rifle, chambered in "8mm (.315")" from well before World War I until at least the 1930s. The British-founded "Rifle Factory Ishapore" continues to manufacture Lee–Enfield sporting rifles in this chambering.

Handloading

Reloadable cartridge cases can be produced by reforming and trimming

When reloading for "wedge-lock" Mannlicher rifles such as the M.88, M.86/88, M.86/90 or M.88/90 chamber pressures should be kept low for safety. Rifles such as the Mannlicher M.95 using a stronger rotating-bolt design can be loaded to higher pressures.
