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.

    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.
