 To replace the Mk III, IV, and V, the Mark VI round was introduced in 1904, using a round nose bullet similar to the Mk II, but with a thinner jacket designed to produce some expansion, though this proved not to be the case.In 1898, APX (Atelier de Puteaux), with their "Balle D" design for the 8mm Lebel cartridge, revolutionised bullet design with the introduction of pointed "spitzer" rounds.In addition to being pointed, the bullet was also much lighter in order to deliver a higher muzzle velocity.
