This was a special round designed and loaded at Frankford Arsenal for use by the U.S. Military. It became the standard .45 Revolver round as issued. The round and casing are shorter than a 11.43x33mmR (.45 Long Colt) to allow it to be chambered in both the Colt 1873 Revolver as well as the Smith & Wesson Schofield Revolver, the S&W Revolver being used primarily by the U.S. Cavalry. Additionally, the round was issued with a solid head and easily replaceable Boxer primer with the intent that a unit could reload the fired casing at a significant cost saving for the ammunition to the Government.
