Summary

The .25 ACP originated in Belgium in 1905. The .25 ACP also has a case length of 0.62 in” (15.75mm) and an overall length of 0.91 in” (23.11mm).

Notes

The .25 ACP, often referred to as the .25 Auto, was created by John Browning in the early 1900s as an alternative to the .22 Long Rifle, in a semi-rimmed Center Fire configuration as opposed to the rimmed/rimfire configuration of the Long Rifle. Today, many Wildcat cartridges such as the Eichelberger Dart series are based off of the .25 ACP configured for both pistol and rifle use, mostly for varminting and small game.

Originally, the .25 ACP was created for use in the FN Herstal Model 1905 Pistol (Also known as the Fabrique Nationale dHerstal), located in Herstal Belgium. The .25 ACP was adequate for pocket carry and personal defense in limited situations but generally was considered too light and underpowered to be considered a true personal protection device, offering low velocities and energy that often came in under the .22 Long Rifle, although more reliable due to the Center Fire design. By today
