     Developed in 1886 as the first military cartridge designed for use with smokeless powder, the original (232 grain) Balle M round-nosed bullet was replaced in 1898 with the Balle D, a solid bronze projectile. It was the Balle D that served the French military through World War I and into the 1930s.
