The 10mm handgun cartridge is renowned for its power, versatility, and flat trajectory. Developed in the early 1980s, the 10mm was designed to bridge the gap between the power of magnum revolver rounds and the capacity of semi-automatic pistols. Initially gaining attention through the FBI’s brief adoption, the 10mm has maintained a dedicated following among gun enthusiasts, law enforcement, and hunters.
The 10mm Auto was introduced in 1983 by firearms manufacturer Dornaus & Dixon in collaboration with firearms expert Jeff Cooper. It was designed to provide magnum-level power in a semi-automatic platform. The FBI adopted the 10mm after the 1986 Miami shootout, finding it more powerful than their existing rounds. However, its recoil proved challenging for some agents, leading to the development of the .40 S&W, a shorter and less powerful version of the 10mm.
The 10mm Auto cartridge typically features a bullet diameter of 10.17mm, with a case length of 25.2mm. It is loaded to a pressure of around 37,500 psi, delivering impressive velocity and energy. Standard loads can propel a 180-grain bullet at speeds exceeding 1,200 feet per second, generating over 600 foot-pounds of energy.
The 10mm is celebrated for its raw power and versatility. It delivers greater energy and penetration than many other handgun calibers, making it suitable for various applications, from self-defense to hunting. Whether for personal protection or outdoor adventures, the 10mm offers unparalleled performance.
