What is the most common gauge for shotguns?

The most common gauge for shotguns is the 12 gauge. This popularity can be attributed to its versatility and effectiveness for a wide range of shooting activities, including hunting, sport shooting, and home defense. The 12 gauge offers a good balance between the amount of shot it delivers and manageable recoil, making it accessible for both novice and experienced shooters.

In practical terms, a 12 gauge shotgun can accommodate various types of ammunition, including birdshot, buckshot, and slugs, which further enhances its utility across different shooting scenarios. Because of these factors combined with its established presence in the firearms market, the 12 gauge remains the prevalent choice among shotgun enthusiasts and professionals alike.

Other gauges like 16, 20, and 10 can be useful in specific contexts or preferences, but they do not match the widespread acceptance and availability of the 12 gauge in most shooting situations.
