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.

    Very Accurate

    These slugs are fantastic and consistent. I use them for 3 gun competitions and I have never had any problems with them. I shoot them consistently and very accurately out to 100 yards. They can also be used for home defense and hunting as they pack a punch.

    Cost Per Round $1.88 per round

    These magnum 12 gauge shells from Hornady were made specifically for coyote hunting: a practice which not only nets warm meals and nice pelts but helps control the population of an invasive, potentially disease-spreading species while protecting smaller game targets for harvesting during the appropriate seasons. This shotshell's hull measures three inches in length and contains a powerful powder charge for increased effectiveness out to 50 yards. The shot load comprises 1-1/2 ounces of BB sized (.18 caliber) birdshot which offers devastating energy with minimal fur damage.

    In addition, the shot has been nickel-plated which gives it extra hardness and ability to stay rounded during firing; this shrinks patterns, ensures performance at distance, and allows for deeper penetration into the vital organs inside the chest cavity. The shot resides within Hornady's Versatite wad (same design as Federal's Flitecontrol) which exits the muzzle with the shot before braking to the rear after a few feet, dramatically reducing pattern diameter for dense, hard-hitting effect. Hornady powers the shell with their own blend of clean-burning propellant which is ignited by a reliable 209 primer.

    The 12 gauge shotgun has been since the 1870's and remains one of the most powerful and popular firearms to this day. Proven through nearly a century and a half of civilian, military, and law enforcement use, the 12 gauge is great for several shooting applications including hunting, sports shooting and home defense.

    Since 1866, Winchester has been making some of America's favorite ammunition. They have earned a reputation for producing high quality ammo that is made in the USA. These Super-X shells are a great choice for hunting and self defense applications.

    Each hull is 3" long and carries 24 pellets of #1 Buffered buckshot. Firing at 1040 feet per second, these shells offer tight patterns and hard hitting knockdown power. Pick up this bulk priced case of 250 rounds and you are set for several range and hunting trips!

    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!

    These 12 gauge 00 buckshot shells from Federal's Vital-Shok line are a small step up from budget loads that offer a bit more performance in both the hunting and home defense realms. Each of the nine 00 buck pellets in this shell is plated with copper, allowing the shot to resist deformation during barrel travel, an effort that is assisted by a cupped wad. Rounder pellets fly farther, group more closely together, and hit harder with penetrating power that will cause massive disruption in the chest cavity of a deer or an assailant.

    When fired, the wad's piston-like bottom portion will collapse to reduce felt recoil while its skirt will flare outwards for efficient gas capture, contributing to consistent muzzle velocities. These components, along with clean-burning powder and a 209 primer, are contained within a high-brass head and moisture-repelling plastic hull. The reloadable hull has a strong crimp up top, a rolled edge for seamless insertion, and an unfolded length of 2-3/4 inches for safe compatibility with the most common 12 gauge shotgun chamber sizes.

    If you live in a state or territory that doesn't allow rifle calibers for hunting or simply love the versatility of a 12 gauge shotgun with interchangeable barrels, you'll find that the prize inside this box from Hornady's Superformance brand is made just for you. Intended for use with rifled barrels, this shell profile consists of a sabot with a massive 300-grain Monoflex slug. The Monoflex design is made with an all-copper body with a pre-skived hollow cavity that is filled with a flexible polymer tip. This configuration produces aerodynamic drag resistance in flight for accuracy shots alongside massive expansion with minimal loss in weight during entry into a target.

    The damage inflicted by the heavyweight projectile's expansion is sure to create massive wounds in the vital organs of a deer or small moose at appropriate distances. Each sabot slug is contained within a 2-3/4 inch plastic hull for versatile compatibility and propelled by clean-burning powder and a reliable 209 primer. Hornady's powder burns completely when used, leaving behind no excess residue in the grooves of your rifled barrel.
