The 7.5×57mm MAS or 7.5×58mm mle 1924c was a short-lived French rifle cartridge that was introduced in the mid-1920s to replace the 8×50mmR Lebel, although it itself was soon replaced with the 7.5×54mm French round, that served the French for decades to come until France, along with the rest of NATO, adopted the standard NATO calibers, 5.56×45mm NATO and 7.62×51mm NATO.
The obsolete 8mm Lebel round was powerful and accurate but due to its shape it was particularly poorly suited to automatic weapons with large-capacity magazines.[1] The only weapon ever fielded in 7.5 mm MAS mod. 1924 was the fusil-mitrailleur mle 1924, a light machinegun based on the B.A.R action. Early examples of the FM 24 proved prone to various failures; additionally, it was possible to mistake the new 7.5×57mm for a German 7.92×57mm Mauser round. The Mauser round would chamber and fire, but the larger bullet would not fit in the barrel and could cause a catastrophic malfunction. The new 7.5 mm round was abandoned and replaced by the 7.5×54mm MAS mod. 1929.[2]
