A Brief History of the 10mm Automatic

Origins and Development

The 10mm Auto, also known as the 10mm Automatic, was first introduced by the legendary firearms manufacturer Jeff Cooper in the early 1980s. Cooper envisioned a cartridge that could deliver superior stopping power while still maintaining manageable recoil. This led to the birth of the 10mm Auto, which was initially chambered in the Bren Ten pistol.

Adoption and Decline

Despite its promising start, the 10mm Automatic faced some challenges in the market. Shooters found the recoil to be too harsh for comfortable shooting, which led to a decline in popularity. However, the cartridge’s story took a different turn when it found a second life as the .40 S&W (Smith & Wesson) round. This slightly shorter and lighter version of the 10mm found favor with law enforcement agencies across the United States, boosting its overall recognition.

One of the key attractions of the 10mm Automatic is its formidable ballistics. It offers a significant advantage in terms of stopping power compared to standard 9mm and .45 ACP cartridges. The 10mm’s high velocity and energy make it a top choice for hunting and personal defense.
