20 Gauge Ammo

The 20 gauge shotgun is a favorite of many shooters due its excellent handling and (in guns of similar weight) much lower felt recoil compared to the 12 gauge. 20 gauge ammo shotgun can be used for everything from hunting and trap shooting to self-defense. 20 gauge shotshells have a distinctive yellow hull to help prevent accidental (and dangerous) loading of shells into the wrong size shotgun.

A 20 gauge shotshell typically fires an ounce (give or take 1/8 oz.) of shot at 1,200 feet per second, with steel waterfowl loads typically moving faster. Buckshot loads in 20ga are typically for self-defense, though they may be used for hunting as well. Slugs make the 20 gauge a viable deer gun at 100 yards and beyond, while birdshot is used for target shooting and, of course, birds.

Some 20 gauge loads (particularly waterfowl ones) come in a 3" hull length that packs more shot or propellant into the shell; this produces more recoil, but allows the 20ga to close the power gap with its larger cousins without the need for another shotgun when needed.

At Widener's, you'll find cheap 20 gauge ammo for sale from the biggest names in ammo. Look for Federal, Fiocchi, Winchester and more in-stock at very competitive prices.

    The 20 gauge has been around for years and years, and although it is not the most popular shotgun in the world, it is one of the best. With less recoil and almost as much payload as the 12 gauge, the 20 gauge is phenomenal for shooting for long periods of time at the range and hunting small game but doesn't sacrifice too much payload to prevent you from using it for big game. Whatever type of sport shooting or hunting you have in mind, the 20 gauge has got your back.

    Since its founding in 1855, Winchester has been making some of the best ammunition in the world, causing them to be one of the most popular and trusted ammunition companies in the United States. These Super-X, 2 3/4", hollow point, rifled slugs fire at the astonishing speed of 1600 feet per second, hitting with incredible expansion and energy, great for taking down any boar or deer you may come across. With the quality and reliability of Winchester Super-X in your shotgun, you have no reason to worry.

    20 Gauge shotguns deliver an excellent balance of power and recoil and are used for both sporting and self-defense purposes. This buckshot load from Rio Royal is designed mainly for game hunting, but can work in a home defense role as well.

    Each 2-3/4" shell in this box of 25 fires nine pellets of #1 buckshot at a muzzle velocity of 1,330 feet per second. This is a relatively powerful load that produces considerable felt recoil in lighter shotguns. #1 buckshot is slightly smaller than 00 buck, but works very well for hunting and personal protection and reduces the risk of overpenetration; this latter property is a significant consideration for defensive use in populated areas. Do note that this box might call its shot "three-by-three," which simply refers to how #1 buck stacks in a column when loaded in a 20 Gauge shell.

    Rio Royal is a Spanish shotshell manufacturer with production facilities in both the USA and Spain. Their products are well-liked for their solid performance and reasonable price.

    Whether you hunt with your 20 Gauge shotgun or would use that invaluable piece of hardware to protect your homestead, Aguila’s Mexican-made #2 buck ammo has got you covered!

    This shell is loaded with one ounce of #2 buck (aka 3F, which is just another name for 0.27” diameter shot pellets). Aguila’s hard lead and highly spherical shot pellets ensure a dense and effective pattern at close-to-medium range. The smaller buckshot pellets will give you a thicker spread than conventional 00 buck, which makes it optimal for hunting in areas with lots of intrusive branches and foliage, and the lighter pellets also present a reduced risk of potentially catastrophic over-penetration during a home defense situation.

    This shell’s 1,220 fps muzzle velocity means that its entire shot column has a combined muzzle energy of 1,446 ft lbs – very potent stuff! And thanks to Aguila’s fine-tuned production protocol, which yields consistent ballistic performance and cycling, you can depend on this ammo to do its job exactly when you want it to.

    Turn your trusty 20 gauge into a deer gun with Federal ammunition. Intended to extend the reach of smoothbore shotguns, these shells fire a rifled hollow point slug that can bring deer down at 75 yards--try doing that with buckshot!

    Each 2-3/4" shell in this case of 250 fires a 3/4 oz. hollow point slug at 1,600 feet per second. This ammo provides enhanced accuracy via a plastic ball inserted between the slug and the wad. This helps center the projectile in smoothbore barrels for optimal ballistics.

    Federal Vital-Shok ammunition is made in Anoka, Minnesota, home of Federal since the 1920s.

    These 3-inch shotshells from Federal Premium will bring a huge boost of power and capability to your appropriately chambered 20 gauge piece. Federal ammunition is manufactured in Minnesota using high-quality components that are manufactured in-house and thoroughly checked over for uniform shapes, sizes, and performance. Their ammunition has been trusted to service government contracts as well as to accompany professional competitors to the Olympic games. Their Vital-Shock line in particular calls for very specific parts and treatments to help guarantee excellent results on target.

    These include a crushable wad column which reduces felt-recoil and protects the 1-1/4 ounce load of #2 buckshot from deformation using a tall shot cup. This job is also performed by onboard buffering media and copper-plating which both help to keep the shot pellets perfectly round for tighter shot clouds and deeper penetration. As a result, shooters can use this ammunition for groundhogs, deer, hogs, and even home invaders. The entire arrangement is housed within a moisture-resistant hull with a brass head and powered by clean-burning propellant. Federal arms the shotshell with their own 209 primer for reliable ignition that won't leave mercury or other harmful chemicals behind in your favorite shotgun.
