A shotgun is a long-barreled firearm designed to discharge a specific type of ammunition called a shotshell. Unlike many other firearms, a shotgun can fire numerous small, spherical projectiles known as shot. It is also capable of firing a single, large, solid projectile called a slug.

Shotguns are most commonly smoothbore firearms. This means the inner walls of the barrel lack rifling, or the grooves used to spin a bullet. While rifled barrels exist for shooting sabot slugs, the smoothbore design is the standard. This type of firearm is essential for various tasks, from hunting to specialized military roles.

The mechanism of a shotgun relies on how the projectiles travel through the barrel. Inside a shotshell, the pellets are propelled indirectly by a component called wadding. When the shell is fired, the wadding pushes the shot through the barrel. As the projectiles exit the muzzle, they begin to scatter into a wide pattern.

To manage this spread, many barrels are "choked" at the muzzle end. A choke is a constriction that controls how much the shot scatters upon exit. Because the muzzle energy is divided among many small pellets, each individual projectile has less penetrative kinetic energy than a single large bullet. Additionally, the lack of spin stabilization and the aerodynamic shape of the pellets cause them to decelerate quickly due to drag.

Shotguns vary significantly in their design, caliber, and action types. They are measured in gauges, with 12-gauge (18.53 mm) and 20-gauge (15.63 mm) being the most common bores. Some shotguns are single-shot, while others are repeating models. Non-repeating designs often include over-and-under or side-by-side break action shotguns.

Modern repeating shotguns are frequently pump-action or semi-automatic. Other types include fully automatic, lever-action, and bolt-action models. This variety allows the tool to be adapted for specific needs, such as high-speed target shooting or heavy-duty breaching.

The history of the shotgun traces back to early smoothbore firearms. In 16th-century Europe, fowling pieces appeared as tools for hunting birds. By the 17th century, some barrels were extended to 6 feet to increase accuracy.

The term "shotgun" was first recorded in 1776 in Kentucky. During the 19th century, cavalry troops favored shotguns because they were effective while moving. However, by the late 1800s, rifled firearms began replacing them on battlefields due to better long-range accuracy. The military value of the shotgun was later rediscovered during the First World War. American forces used the pump-action Winchester Model 1897 with great success during trench fighting.

Many inventors contributed to the evolution of the modern shotgun. Daniel Myron LeFever is credited with inventing the American hammerless shotgun in 1878. This design removed the external hammers used on older guns.

John Moses Browning also revolutionized the field. In 1893, he introduced the pump-action design, and in 1900, he patented the Browning Auto-5, which was America's first semi-automatic shotgun.

The Anson and Deeley boxlock patent of 1875 was another major milestone. This design used only four moving parts, making shotguns more reliable and affordable to produce.

Shotguns serve many distinct purposes in the modern world. In hunting, they are ideal for fast-flying birds or agile small game. This is because the pellet spread prevents overpenetration and keeps shots from hitting distant bystanders. In law enforcement and military contexts, the high short-range blunt knockback force makes them useful for door breaching or crowd control.

Recently, shotguns have proven effective in modern conflicts, such as the Russia-Ukraine war. They are used to shoot down enemy drones because the pellet spread makes hitting fast-moving targets much easier.

Beyond combat and hunting, shotguns are central to various target-shooting sports. Athletes participate in disciplines like skeet, trap, and sporting clays. These sports involve shooting at flying clay disks, often called "clay pigeons," which are launched by a device known as a trap.

High-end specialty guns, such as those from Krieghoff or Perazzi, are often used in these prestigious sporting events. These decorated weapons can cost as much as $100,000. From simple tools for defense to highly specialized sporting equipment, the shotgun remains a versatile and significant technology.
