7.5x54mm French MAS Reloading Data

Warning! Notes: Historical Notes: In 1924, the French army adopted a new cartridge, the 7.5x58mm MLE 1924C, for a new automatic rifle. In 1929, to avoid ammunition mix-ups with the 7.92x57mm, the French changed to a 4mm shorter cartridge of slightly larger diameter, creating the 7.5x54mm MLF 1929C. This cartridge was originally used in light machineguns and automatic arms, but in 1934, the Berthier Model-07/15 bolt-action rifle was modified for this round. In 1936, a newly designed bolt-action rifle (MAS 36) in the new 7.5mm was adopted. This rimless cartridge replaced the rimmed 8mm Lebel, which the French army had used since 1886. General Comments: The 7.5mm MAS is in the same class as the 30-40 Krag or the 303 British and can be used for the same range of game. Performance can be improved a little in handloading, but only Berdan-primed military cases have formerly been available. The military load develops about 40,000 psi breech pressure. The initials MAS represent the French arsenal that developed this cartridge and rifle, Manufacture d'Armes de Saint Etienne. (Cartridges of the World 11th Edition)
