Description
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. 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.
