Hunting shells, also known as shotgun shells, are the specialized ammunition used in shotguns for hunting, sport shooting, and home defense. Unlike rifle or handgun cartridges that fire a single projectile, most hunting shells are designed to fire a cluster of small pellets called shot. This design makes them highly effective for hitting moving targets like birds or small mammals.
Choosing the right hunting shell is critical for both the success of your hunt and the safety of the shooter. Using the wrong ammunition can lead to poor performance or even damage your firearm. This guide breaks down the components of a shell, the different sizes available, and how to match your ammunition to the game you are hunting.
The Anatomy of a Hunting Shell
To understand how a hunting shell works, it is helpful to know what is inside the casing. Each component plays a specific role in ensuring the shot travels accurately and with enough force to reach the target.
The Hull: This is the outer plastic or paper tube that holds all the other components together. It is usually color-coded by gauge to help hunters avoid mixing up different sizes of ammunition.
The Primer: Located at the center of the brass base, the primer is a small chemical cap. When the shotgun’s firing pin strikes the primer, it creates a spark that ignites the gunpowder.
The Gunpowder: This propellant burns rapidly when ignited, creating high-pressure gas. This gas pushes the contents of the shell out of the barrel at high speeds.
The Wad: Usually made of plastic or felt, the wad sits between the powder and the shot. It acts as a seal to prevent gas from leaking past the pellets and helps guide the shot smoothly out of the barrel.
The Shot: These are the actual projectiles. Depending on the shell type, this could be hundreds of tiny lead pellets or a single large heavy metal slug.
Understanding Shotgun Gauges
The “gauge” refers to the inner diameter of the shotgun barrel and the corresponding size of the shell. A unique aspect of the gauge system is that a smaller number actually represents a larger barrel diameter.
- 12-Gauge: This is the most popular and versatile size for hunting. It is powerful enough for large game like deer or turkey but can be used for smaller birds as well.
- 20-Gauge: This is a smaller, lighter shell with less recoil than a 12-gauge. It is an excellent choice for younger hunters, smaller-framed individuals, or upland bird hunting.
- 28-Gauge: This is a specialized size often used for small game and clay pigeon shooting. It offers very low recoil but requires more precision from the shooter.
- .410 Bore: Technically a measurement of caliber rather than gauge, the .410 is the smallest common shotgun shell. It is typically used for very small game or by expert shooters looking for a challenge.
It is vital to only use shells that match the gauge stamped on your shotgun’s barrel. Attempting to fire a 20-gauge shell in a 12-gauge shotgun can cause a dangerous obstruction.
Shot Sizes and Numbers
The pellets inside a hunting shell come in various sizes, which are categorized by numbers. Just like gauges, the numbering system for shot is inverse: the larger the number, the smaller the individual pellets.
Birdshot
Birdshot consists of many small pellets and is used for birds and small mammals. Common sizes include #7, #8, and #9, which are used for small birds like dove or quail. Larger birdshot, such as #4 or #5, is often used for pheasants and ducks.
Buckshot
Buckshot contains much larger pellets than birdshot and is designed for larger game. The most common size is 00 (pronounced “double-aught”) buckshot. Because the pellets are larger, there are fewer of them in each shell, but each one carries significant energy.
Slugs
A slug is a single, solid projectile fired from a shotgun. Slugs are used when a hunter needs the maximum amount of power and range, typically for hunting deer or wild boar in areas where rifles are not permitted.
Choosing the Right Material
The material used to make the shot is just as important as the size. Traditionally, lead was the standard material because it is heavy and inexpensive. However, environmental regulations and performance needs have introduced other options.
- Lead Shot: This remains the most common choice for upland bird hunting and target practice. It is dense and retains its energy well over long distances.
- Steel Shot: Steel is required by law for waterfowl hunting in many regions because it is non-toxic. It is lighter and harder than lead, meaning it travels faster but loses energy more quickly.
- Tungsten and Bismuth: These are premium non-toxic alternatives. They are denser than steel and sometimes even denser than lead, providing superior range and knockdown power for specialized hunts.
Matching the Shell to the Game
To be an effective hunter, you must match the shell’s power and shot size to the animal you are pursuing. Using shot that is too small may not humanely harvest the animal, while shot that is too large can damage the meat.
Small Game and Upland Birds
For rabbits, squirrels, quail, and doves, a 12-gauge or 20-gauge shell with #6, #7.5, or #8 shot is usually sufficient. These targets are relatively fragile, so a high volume of small pellets increases the chance of a successful hit.
Waterfowl
Ducks and geese require larger shot sizes and non-toxic materials. For ducks, #2 or #4 steel shot is standard. For larger geese, BB or BBB steel shot is often preferred to penetrate their thick feathers and down.
Turkey Hunting
Turkey hunting requires specialized shells often labeled as “Turkey Loads.” These are high-powered shells usually containing #4, #5, or #6 shot. They are designed to produce a very tight pattern to ensure a clean shot at the bird’s head and neck.
Big Game
When hunting deer with a shotgun, hunters typically choose between 00 buckshot or slugs. Buckshot is effective at close ranges (under 40 yards), while slugs can be used accurately at 75 to 100 yards depending on the shotgun’s barrel and sights.
Shell Length and Chamber Size
In addition to gauge and shot size, you must consider the length of the shell. Common lengths include 2 ¾ inches, 3 inches, and 3 ½ inches. The length refers to the size of the shell after it has been fired and the crimp has opened.
Your shotgun will have a specific chamber length stamped on the barrel. You can safely fire shells that are shorter than or equal to your chamber length, but never longer. For example, a shotgun with a 3-inch chamber can fire 2 ¾-inch and 3-inch shells, but it cannot fire 3 ½-inch shells.
Safety and Storage Tips
Handling hunting shells requires a commitment to safety. Always double-check your ammunition before loading it into your firearm to ensure it is the correct gauge and length.
Store your shells in a cool, dry place. Moisture can corrode the brass base or cause the gunpowder to degrade, leading to misfires. Many hunters use plastic ammo cans with rubber seals to keep their shells in peak condition for years.
Finally, always dispose of spent hulls properly. Leaving empty plastic shells in the woods is considered littering and can harm the environment. Most hunters carry a small pouch or use their pockets to collect empties for recycling or disposal.
Conclusion
Understanding the nuances of hunting shells is a fundamental skill for any hunter. By choosing the correct gauge, shot size, and material, you ensure that your equipment performs reliably and ethically in the field. Remember to always check your shotgun’s barrel for compatibility and follow local regulations regarding shot material.
