.40 S&W/10mm

About 10mm and .40 Bullets

10mm ammo was introduced back in 1983 as a semi-automatic pistol cartridge, then known as 10mm Auto. The round was briefly used by the FBI but was later decommissioned due to the excessive recoil it produced. A reduced-recoil round was created in response to this known as "10mm Lite." Later, Smith & Wesson created a new version of the 10mm round with a shorter casing, allowing for use in smaller semi-automatic handguns. This became known as the .40 Smith & Wesson often referred to as .40 S&W or just "forty cal." The handgun cartridge has since become popular among law enforcement, while the 10mm Auto is still relatively popular as well.
