12-Gauge Shotgun Load Types
The 12-gauge shotgun is one of the most versatile firearms you can own. With so many options for shot loads, how do you know which 12-gauge ammo shot patterns work best for you? From options ranging from hundreds of tiny beads to a single heavy slug, there’s plenty that you can do with your 12-gauge shotgun.
Understanding the different 12-gauge ammo shot patterns, as well as their best applications, will make you more productive in the field.
Possibly the most common type of 12-gauge shotgun load, birdshot comes in a variety of sizes. A variety of 12-gauge ammo shot patterns allow hunters to target game from small to medium sizes. For birdshot, the larger the number, the smaller the pellet. With smaller pellets, you also get more pellets in a single load. For example, a shotgun shell with #9 shot will hold more total pellets than one loaded with #1 shot.
At only 0.08 inches of diameter per pellet, #9 shot is one of the smallest sizes you’ll find. In most cases, this load is not used for live birds, but for clay pigeons. However, it’s also useful as a snake shot and for eliminating small birds; if this shot is used to kill something, it’s usually pest control, not game hunting.

#8 1/2 Shot
With a diameter of .085 inches per pellet, this shot is not much larger than #9, but it does give slightly more weight to each pellet, which makes it useful for sporting clays and trap shooting at slightly longer distances.

Birdshot #8 & Under
Offering more power per pellet, the #8 shot remains popular for clay-pigeon shooting, but can also be used for some of the smallest game birds, such as rabbit, squirrel, and doves, but you’ll need to be close to do any real damage. Just be aware that animals taken with this shot will be full of many small pellets, making cleaning and eating more difficult.

#7 1/2 Shot
Sometimes called the “dove shot,” this is about the smallest legitimate hunting load. With pellets that are .1 inches in diameter, this load can be used for doves, pheasant, and ducks, assuming they are within close range. This is also a versatile load that can be used for smaller game and trap if necessary.

With good range and limited damage to the meat, #7 is an ideal load for pheasant, grouse, and dove. The shot is also one of the largest that is still ideal for trap shooting and shotgun-competition sports.

Birdshot #6 For Medium-Large Bird Hunting
Moving into #6 shot allows you to begin pursuing medium-sized and even larger birds, and it’s generally the smallest load used for pheasant or duck if distance is a factor, which it almost always is. At .11 inches in diameter, this is pretty much the middle ground for birdshot, and can be used effectively for a variety of game from squirrels to turkey, assuming, of course, you hit the turkey in the head.

#5-6-7 Shot Mix
This is an interesting load that mixes #5, 6, and 7 shot into one shell. It’s primarily advertised to turkey hunters, and it’s best for open-field hunting where shot distance can be hard to estimate. They are usually loaded into larger shells of three inches.

#4 shot, which should not be confused with #4 buck, has a pellet diameter of .13, giving each pellet greater force and penetration. It is commonly used as a turkey load, but can also be used for a variety of game birds. It’s also the smallest load that is considered effective for home defense, as #4 can deliver effective power without penetrating walls.

Birdshot #3 & Under
This ammunition is great for multiple applications, and hunters will find it effective for many different upland game birds, as well as waterfowl. Because of the thickness (.14 inches per pellet, #3 shot could be used for geese, although some may feel #3 is still too small.

With heavy pellets and the ability to place effective penetration at 40 yards, the #2 shot is one of the favorite loads for goose hunters. The pellet size is .15 inches, giving enough power for geese while remaining effective for distance shots on ducks and other waterfowl.

BB Shot: 12-Gauge Ammo Shot Patterns
You might think “BB” means a small toy gun for children, but a 12-gauge shotgun shell loaded with BB shot, which measures .18 inches, is an effective hunting load.

There is also the smaller “B” pellets (.17 inches), as well as the larger “BBB” pellets (.19).

Buckshot: 12-Gauge Ammo Shot Patterns

#00 buckshot, usually called simply “double aught,” is an effective round that can be used for deer hunting, but also has applications in larger game, including heavy hog and even large game animals found in the western United States. Usually holding about eight .32-inch pellets, the #00 shot delivers reliable penetration and energy transfer.

Three-inch 12-gauge round loaded with #000 buckshot hold around eight or ten .36-inch pellets, so you can imagine how devastating it can be when it impacts a deer or game animal. This is one of the most devastating rounds for shotguns, and can be used for a wide variety of animals, although some consider it not powerful enough (and therefore unethical) to use on significantly large game like moose and bear.

Slugs: 12-Gauge Ammo Shot Patterns
“Slug” is essentially the term used to describe a shotgun bullet. These are one solid piece of lead, making them the most powerful ammunition for 12-gauge shotguns, but also the most difficult to place properly, as there is no spread. They are used primarily for whitetail deer hunting, as well as the pursuit of hog, black bear, and similarly-sized game.
Buying Guide: Hornady 12-Gauge 2-3/4″ Lead Slug
A rifled slug has spiraling grooves on the body of the projectile, giving it a spin that increases accuracy. Rifled slugs are generally useful for long-distance shots, although most rifled slugs will not perform better than a true rifle shot. The advantage to rifled slugs is that they give better accuracy in a smooth-bore barrel.

A sabot slug is thinner and longer, and the slug itself is wrapped in a casing, called the “sabot” (pronounced “say-bo”) that ensures a seal between the projectile and the barrel. Sabot slugs do not have rifling, so these are primarily used in shotguns with rifled barrels.
