12 Gauge Ammo

12 gauge shotshells are versatile tools for every purpose: hunting, self-defense, law enforcement, and even military operations. The 12 gauge has a bore of about .73 inches or 18.53mm; shells for it come in a wide variety of configurations for different purposes. Standard length 2-3/4"" shells offer less firepower than "magnum" 3-inch shells, but produce lower recoil; magnum shells are generally used only for hunting. You'll find 12 gauge ammo for hunters, trapshooters, and self-defense for sale here at Widener's.

In general, 12ga. hunting loads typically fire 8-10 pellets of 00 buckshot at a muzzle velocity of around 1,325 feet per second; self-defense loads often produce around 1,200 feet per second in order to reduce recoil and overpenetration risk. Slugs, on the other hand, fire a large projectile (usually about one ounce) at a much higher velocity to extend the shotgun's reach. Some slugs use a saboted design intended for a rifled barrel only.

While not suited for self-defense or deer hunting, birdshot loads are a great choice for bird hunting or target shooting. 12 gauge shotguns are the standard for sporting clays, a sport vaguely reminiscent of golf that is played over several prepared positions with clay pigeons.

Steel birdshot loads in particular are a must have for waterfowl hunting, as environmental protection laws typically prohibit the use of lead shot in aquatic habitats.

    While they offer stronger recoil and require use in shotguns with larger chambers, these 3-inch 12 gauge shells produce massive energy and carry a heavy payload of fifteen 00 Buckshot pellets; when used on deer, coyotes, and human attackers, fifteen .33 caliber pellets each creating their own wound cavity within close proximity of each other delivers unparalleled physical trauma, making these shells a powerful choice for hunting and self-protection. Buying in bulk with this 150-round case allows for tons of consistent practice.

    The bulk box breaks down into ten smaller packages which contain 15 rounds each. The shotshell profile is built using a brass head that is attached to a reloadable, moisture-resistant plastic hull. The hull's tight, burned crimp prevents moisture from ruining the shell's function when being carried through humid environments. The 15 pellets of 00 Buck pellets are pushed by Winchester's own clean-burning powder which is ignited by a non-corrosive 209 primer.

    Each of these 12 gauge shells from Winchester has a total length of 3 inches which allows for a greater powder charge as well as a 15-pellet payload of 00 buckshot; this translates to a greater effective range, more muzzle velocity, and several more projectiles entering the target and delivering heart-stopping energy. This shot load is contained within a moisture-resistant hull that has a strong crimp with a centered burn for maximum stability in humid environments.

    The rear of the shell comprises a brass head which will stand up to multiple reloading cycles and subsequent extraction. It carries a clean-igniting 209 primer which is the very same that Winchester sells in component quantities to home reloaders. Each shell is also fueled by Winchester's own clean-burning propellant which produces less residue while offering more consistent muzzle velocities.

    This 12 gauge ammunition from Federal Tactical is designed for law enforcement use but can also serve well in a self-defense role. These shells feature the Flitecontrol rear-breaking wad, a design that keeps shot bunched together for several yards after it leaves a shotgun's barrel. This results in tighter patterning for better medium-range effectiveness without sacrificing point-blank lethality.

    Each 2-3/4" shell in this box fires 8 pellets of 00 buckshot at a muzzle velocity of 1,145 feet per second. This velocity is considerably lower than that produced by hunting loads and serves to keep recoil to a manageable level for faster follow-up shots and mitigate the risk of overpenetration.

    Federal Tactical shotshells are loaded in Anoka, Minnesota. This box contains 5 shells, so pick up a few for training and home protection!

    This high-velocity 12 gauge buckshot load from Winchester's Double-X series excels at hunting or defense against predators.

    Each 2-3/4" shell in this box of 5 fires a 9-pellet load of copper-plated 00 buckshot at 1,450 feet per second. This is about 10% faster than typical full-power buckshot loads and results in better medium-range patterning and penetration at the cost of higher recoil.

    Winchester shotshells are loaded in Oxford, Mississippi using reliable 209 primers and Grex polymer buffering to reduce shot deformation.
