11×59mmR Gras

France's first modern military cartridge, the 11×59mmR Gras was introduced in 1874 and continued in service in various roles and with various users until after World War II.

The 11×59mmR was a rimmed, slightly bottlenecked, centerfire rifle cartridge with an external Berdan primer, developed for use in the single shot, bolt actioned Fusil Gras mle 1874.

[3] An improved cartridge was introduced in 1879 with a slower burning F3 powder, alterations to the tip of the bullet and a reduction in the height of the patch.

In 1884 a bullet was introduced of 5% antimony and 95% lead which was compressed and hardened instead of simply cast, and the tip was flattened to improve accuracy.

[1][5][6][7] In 1886 it was replaced in French frontline service by the revolutionary 8×50mmR Lebel, the first military cartridge to use smokeless gunpowder.
