8x50R Lebel

The 8mm Lebel cartridge was the world’s first small-bore (as per late 19th century standards) military round that was loaded with smokeless powder. Adopted by French army in 1886, it served as a primary rifle and machine gun round in French army until mid-1930s, and for much longer period in French colonies. It was used in bolt-action and semi-automatic rifles and some machine guns, all of French origins. Today this round is completely obsolete.
