12 gauge

12-gauge shotgun is a type of firearm commonly used for hunting, sport shooting, and sometimes home defense. The term “12-gauge” refers to the bore diameter of the shotgun, which is approximately 0.729 inches (18.5 mm). The gauge system is based on the number of lead balls of that diameter that would equal one pound—hence, 12 gauge means 12 lead balls would weigh a pound.

Shotguns in this gauge can fire various types of ammunition, such as buckshot, birdshot, and slugs, making them versatile for different applications. Would you like more information on its uses or history?
