The .38-56 Winchester Center Fire cartridge was introduced in 1887 by Winchester for the Winchester Model 1886,[3] and was also used in the Marlin Model of 1895. Production of Model 1886s chambered in this cartridge ceased in 1910 due to lack of demand,[4] while most commercial production of the cartridge itself ceased in the 1930s. New production loaded cartridges and unloaded brass cases are rare, and are often created using reformed .45-70 brass. The cartridge was originally intended to outperform the similar .38-55 Winchester, but in reality had very similar ballistics despite using more gunpowder.[5]
