About 12 Gauge Ammo

Originating in the 19th century, the 12 gauge shotgun shell quickly established itself as a versatile and popular choice in the realm of ammunition, thanks to its balanced size which provided sufficient power for a variety of applications while maintaining manageable recoil.

The gauge system from which it derives its name is based on the number of lead balls of the bore’s diameter required to make up a pound; in the case of the 12 gauge, this equates to 12 lead balls.

Originally loaded with black powder, the transition to smokeless powder in the late 19th to early 20th century marked a significant advancement, enhancing the shell’s energy output, reducing fouling, and minimizing recoil.

The mid-20th century brought further innovations with the adoption of plastic in shotgun shell manufacturing, a material switch that greatly improved weather resistance and durability compared to the previously used paper and brass designs.

Concurrent improvements in shot and wad designs led to enhanced performance and patterning, solidifying the 12 gauge’s reputation in both hunting and sport shooting circles.

Its versatility has made the 12 gauge a favorite among diverse groups ranging from hunters and sport shooters to law enforcement and individuals seeking a reliable home defense solution.

Whether used for hunting various game, from birds to deer, or participating in clay target sports like trap, skeet, and sporting clays, the 12 gauge has proven itself to be adept across numerous scenarios.

Additionally, its formidable stopping power, coupled with specialized self-defense ammunition, has established it as a trusted choice in personal protection.

In the 21st century, the 12 gauge continues to evolve with manufacturers offering a plethora of loads tailored for specific needs, ranging from low-recoil target loads to powerful buckshot and slugs suited for hunting and self-defense.

This ongoing innovation ensures that the 12 gauge shotgun shell remains a prevalent and favored option in ammunition, with its balanced characteristics ensuring its popularity for years to come.

Components of a Shotgun Shell

A shotgun shell is a self-contained cartridge filled with metallic 'shots' - small spherical projectiles contained in a plastic or paper tube called a hull.

Located beneath the shot is the wad or wadding. Usually constructed from paper or plastic, the wadding creates a barrier between the shot and the powder.

Although original 12 Gauge Shotgun Ammo used black powder, today's 12 Gauge Ammo utilizes smokeless powder.

The Shot: A shotgun shell is a self-contained cartridge filled with metallic 'shots' - small spherical projectiles contained in a plastic or paper tube called a hull.

Most shots are made from metal (lead, steel, tungsten, or bismuth). However, non-lethal shotgun shells can be loaded with rubber, rock salt, or small bean bags.

The Wad: Located beneath the shot is the wad or wadding, usually constructed from paper or plastic. The primary purpose of the wad is to prevent the shot and powder from mixing and provide a seal that prevents gas from blowing through the shot rather than propelling it.

The Powder: Original 12 Gauge Shotgun Shells initially used black powder. However, today's modern 12 Gauge Ammo utilizes a far more efficient smokeless powder that takes up far less space.

The Hull: Usually made from paper or plastic, the hull is a tube often capped at the base by a metallic head cover that retains a primer, and a wadding inside the case typically contains the shot charge.
