Which firearm is most commonly used for shooting moving targets in the air?

A shotgun is most commonly used for shooting moving targets in the air due to its design and functionality. When targeting flying game, such as birds, shotguns are preferred because they fire multiple small pellets (shot) rather than a single projectile. This spread increases the likelihood of hitting fast-moving targets that are difficult to aim at with precision.

Shotguns are specifically designed to accommodate this style of shooting, often featuring specialized chokes that affect how the shot spreads. This allows for better chances of hitting moving targets over a larger area, especially when the shooter must lead the target to compensate for its speed and flight path.

In contrast, rifles and pistols are generally suited for precise, stationary, or slower-moving targets rather than those moving quickly in the air. A crossbow is also not ideal for this purpose, as it typically fires a single bolt and requires more time to aim and reload, making it less effective for dynamic shooting situations.
