Intended Use: The 10mm Auto is ideal for a wide range of applications. Its powerful ballistics make it suitable for self-defense and law enforcement, where stopping power and penetration are crucial. Additionally, its effectiveness on medium-sized game at close to intermediate ranges makes it a favorite among handgun hunters. The 10mm Auto is also popular in competitive shooting circuits for its accuracy and flat trajectory.

Caliber/Size: The 10mm Auto was developed to offer a step up in power and range over the 9mm and .45 ACP, providing a high-velocity, high-energy cartridge capable of handling a variety of shooting and hunting scenarios. Its dimensions allow for use in medium to large frame semi-automatic pistols.

Performance Characteristics: Known for its flat shooting trajectory and impressive stopping power, the 10mm Auto delivers high velocity and energy, capable of accurate performance at extended ranges. Modern bullet technology has further enhanced its versatility, offering loads optimized for everything from personal defense to big game hunting.

Material and Construction: 10mm Auto rounds are made with high-quality components, featuring brass casings and a range of bullet designs to cater to specific needs. Options include full metal jacket (FMJ) for practice and competition, jacketed hollow point (JHP) for self-defense, and hard-cast bullets for hunting, ensuring effectiveness across various scenarios.

These brands offer 10mm Auto shooters a broad selection of ammunition choices that meet high standards of reliability and effectiveness.

A Brief History: The 10mm Auto was introduced in 1983, designed to provide FBI agents with a more powerful handgun cartridge following the 1986 Miami shootout. Although the FBI eventually adopted the .40 S&W, a reduced-power version of the 10mm Auto, the original cartridge has maintained a loyal following among shooters who appreciate its superior performance.
