There are two 8 mm Lebel cartridges, one for the Lebel Model 1886 rifle and one for the Modèle 1892 revolver. They are entirely different cartridges and are not interchangeable. The use of the term "Lebel" for the French Mle 1892 revolver and its ammunition was never applied by the French military but has become informally accepted outside of France without any real justification .
