Shotguns are firearms that are designed to fire a spread of pellets, rather than a single projectile. This makes them ideal for hunting birds and small game, as well as for self-defense.

The basic design of a shotgun is similar to that of a rifle. There is a barrel, a receiver, and a stock. The barrel is where the pellets are loaded and fired, and the receiver is where the firing mechanism is housed. The stock is the part of the shotgun that the shooter holds onto.

Shotguns come in a variety of sizes and gauges. The gauge of a shotgun is determined by the number of lead balls that are required to equal one pound. For example, a 12-gauge shotgun requires 12 lead balls to equal one pound. The most common shotgun gauges are 12-gauge, 16-gauge, 20-gauge, and 28-gauge.

Shotguns can also be classified by their action type. The most common action types are break-action, pump-action, and semi-automatic.

Break-action shotguns are the oldest and most common type of shotgun. To load a break-action shotgun, the shooter breaks open the barrel and inserts the shells into the chamber. When the shotgun is closed, the shells are held in place by the extractor. To fire the shotgun, the shooter simply pulls the trigger.

Pump-action shotguns are a more modern type of shotgun. To load a pump-action shotgun, the shooter pumps the forend back and forth. This action ejects the spent shell and chambers a new round. To fire the shotgun, the shooter simply pulls the trigger.

Semi-automatic shotguns are the most advanced type of shotgun. To load a semi-automatic shotgun, the shooter inserts the shells into the magazine. When the shotgun is fired, the recoil from the shot cycle the action, which ejects the spent shell and chambers a new round. The shooter can then continue to fire the shotgun without having to manually cycle the action.

Shotguns are versatile firearms that can be used for a variety of purposes. They are ideal for hunting birds and small game, as well as for self-defense.
