410 Ammo | .410 Bore Shotgun Shells

About .410 Bore Ammo

.410 bore ammo is shotgun ammunition identified by its bore diameter rather than the traditional gauge system used for 12 gauge, 16 gauge, 20 gauge, and 28 gauge ammunition. The .410 is one of the smallest commonly encountered shotgun bore sizes and is known for lightweight firearms, relatively small shot payloads, and a wide variety of field and sporting applications.

.410 shotgun shells are commonly used for small game hunting, upland hunting, recreational shooting, skeet, and other clay target disciplines. Loads are available with birdshot and slugs as well as specialty ammunition designed for specific applications.

Choosing .410 Ammo

Selecting the right .410 ammunition starts with the firearm and its chamber specifications.

Important characteristics include:

• Shell Length: 2 1/2 inch and 3 inch shells are common.

• Shot Size: Different pellet sizes are available for target shooting, upland birds, and small game.

• Payload Weight: Shot weight varies significantly depending on shell length and ammunition design.

• Velocity: Different loads use different velocities depending on their intended application.

• Projectile Type: .410 ammunition is available with birdshot and rifled slugs as well as specialty projectile configurations.

• Shot Material: Lead, steel, and other non toxic shot materials may be available depending on the load.

Always verify the chamber markings and firearm manufacturer's specifications before selecting ammunition.

2 1/2 Inch vs 3 Inch .410 Shells

Two of the most common .410 shell lengths are 2 1/2 inches and 3 inches.

A typical 2 1/2 inch birdshot load may use a lighter payload, while many 3 inch field loads provide additional case capacity for heavier shot charges.

Payload should still be checked on the individual ammunition specifications rather than assumed from shell length alone.

Only use shell lengths approved for the specific firearm. A shotgun chambered for one shell length should not be assumed compatible with another without confirming the firearm manufacturer's specifications.

.410 Birdshot

Birdshot is one of the most common forms of .410 ammunition and is used for clay targets, upland birds, and small game.

Common shot sizes include:

• #9: Frequently used for skeet and clay target shooting

• #8: Target shooting and smaller upland applications

• #7.5: Clay shooting, dove, and upland applications

• #6: Upland birds and small game

• #4: Larger pellets for certain field applications

Shot size numbers work in reverse. As the shot size number decreases, pellet diameter increases.

Smaller pellets allow more pellets within a given payload weight, while larger pellets provide greater individual pellet mass.

.410 Hunting Ammo

The .410 has a long history as a small game and upland hunting cartridge.

Common applications include:

• Rabbit

• Squirrel

• Dove

• Quail

• Other small game

• Certain upland bird applications

The appropriate load depends on the game, expected distance, choke, shot material, payload, and applicable hunting regulations.

Because the .410 generally carries a smaller shot payload than larger shotgun gauges, ammunition selection, patterning, and shooting distance can be especially important.

.410 Target Ammo

The .410 is used in skeet and other clay target disciplines and is often considered a challenging sub bore option.

Target loads commonly use smaller shot sizes such as #7.5, #8, #8.5, or #9.

Although .410 ammunition can produce relatively mild recoil in many firearm and ammunition combinations, the smaller shot payload generally produces fewer pellets than larger gauge target loads. This can result in a smaller margin for error when breaking clay targets.

Actual felt recoil depends on firearm weight, payload weight, ammunition velocity, stock design, and firearm fit.

.410 Rifled Slugs

Some .410 ammunition uses a single rifled slug rather than multiple shot pellets.

A slug load functions differently from birdshot because it launches one projectile instead of a pattern of individual pellets.

Slug weight, velocity, firearm compatibility, and intended use vary considerably between manufacturers and individual products. Shooters should follow the ammunition and firearm manufacturers' specifications when selecting a .410 slug load.

.410 Bore vs 28 Gauge

The .410 bore and 28 gauge are both commonly found in lightweight field and sporting shotguns, but their names are based on different measurement systems.

The .410 is identified approximately by bore diameter, while 28 gauge uses the traditional shotgun gauge system.

Traditional 28 gauge loads generally provide greater shot payload capacity than many common .410 loads. The additional pellets can produce a denser pattern, while the .410 offers its own advantages in lightweight firearms and challenging sub bore target shooting.

The best choice depends on firearm fit, intended application, ammunition availability, recoil characteristics, and shooter preference.

Why Is It Called .410 Bore Instead of 410 Gauge?

The terms “410 gauge” and “410 ammo” are commonly used conversationally and in online searches, but .410 bore is the more technically accurate designation.

Traditional shotgun gauges such as 12, 16, 20, and 28 gauge are based on the historic gauge measurement system.

The .410 is different because its designation refers approximately to the diameter of the bore in inches.

This is why ammunition manufacturers frequently label their products “.410 Bore” even though the phrase “410 gauge” remains widely used.

.410 Ammo FAQs

What is .410 ammo?

.410 ammo is shotgun ammunition designed for firearms chambered in .410 bore. Unlike traditional shotgun gauges, the .410 designation refers approximately to bore diameter.

Is it .410 bore or 410 gauge?

.410 bore is the more technically accurate term. “410 gauge” is nevertheless widely used informally when referring to .410 shotguns and ammunition.

What lengths are .410 shotgun shells?

2 1/2 inch and 3 inch .410 shells are common. Always verify the firearm's chamber markings and manufacturer specifications before selecting ammunition.

What shot sizes are available in .410 ammo?

Common birdshot sizes include #9, #8, #7.5, #6, and #4, although specific availability varies by manufacturer and ammunition type.

What is .410 birdshot used for?

Depending on the specific load, .410 birdshot is commonly used for clay target shooting, small game, dove, quail, and other upland applications.

Are .410 slugs available?

Yes. .410 ammunition is available with rifled slugs that use a single projectile instead of multiple shot pellets.

Does .410 have less recoil than 20 gauge?

Many .410 firearm and ammunition combinations produce relatively mild recoil, but gauge or bore diameter alone does not determine recoil. Firearm weight, payload, velocity, stock design, and fit all affect felt recoil.

What is the difference between .410 and 28 gauge?

The .410 is identified by bore diameter, while 28 gauge uses the traditional shotgun gauge measurement system. Traditional 28 gauge ammunition generally carries a larger shot payload than many common .410 loads.
