Picking The Right 12-Gauge Ammo

Gun News

Whether for home defense or hunting, a 12-gauge shotgun is most effective when paired with the right load of 12-gauge ammo.

Shotguns are among the most versatile firearms in existence. And in this class of gun, the 12-gauge reigns supreme.

Hunting, home defense, recreation–nine times out of 10, shooters opt for the good ol’ 12 bore. Further aiding its popularity, the wide variety of 12-gauge ammo available today for nearly any application.

Such a wealth of loads is a blessing and a curse. On the one hand, no matter how specialized, likely there’s a load tailored for it. On the other hand, how the heck do you know which of the hundreds of options to use?

We’ll hash this out a bit in this 12-gauge ammo guide, go over what’s used for what and help you figure out the best shells for your purpose.

12-Gauge Ammo: Deciding Your Purpose

Like so much in the shooting world, decisions are best made by defining your particular parameters. A dove hunter requires a much different shell than a LEO breaching a door.

Additionally, not only would using the wrong load for the wrong situation be suboptimal, but it can also be dangerous for yourself and others. For example, one wouldn’t want to try and stop a home invader with birdshot, and one wouldn’t want to try and stop a bird with buckshot.

The former case may only result in an even angrier intruder and the latter with a puff of red mist and feathers. Shotguns are only as versatile as they are because of the wildly different styles of projectiles they can fire, so it’s important to use the appropriate type for the task at hand.

Besides selecting 12-gauge ammo based on its inherent physical traits, other factors come into play as well such as local laws and regulations. For example, California legally requires that lead-free ammunition be used when hunting due to the state’s environmental concerns. Someone hunting in California would need to select something that complies with the lead-free requirement when choosing their load.

For every conceivable realistic use that a shotgun has, there are numerous loads of 12-gauge ammo that fit the bill. The trick to getting the most out of the gun is knowing how to pick the right load for the job.

Choosing The Right 12-Gauge Ammo:

When it comes to hunting with a shotgun, the general type of load that should be used is pretty cut and dry. Birds and varmints are generally best dispatched with some kind of birdshot, and medium to large game is best dealt with using slugs or buckshot depending on various factors.

When it comes to the realm of 12-gauge home defense ammo, however, the choice between buckshot and slugs is less clear. While the two types of loads are both good for self-defense, they achieve their performance in very different ways.

Buckshot

Buckshot loadings create dynamic wound channels and energy transfer by firing multiple pellets. The pellets in a load of buckshot are fewer than those in birdshot but are significantly larger in diameter.

For example, common 2 ¾-inch shells of 00 buck are typically loaded with eight .330-inch diameter projectiles. With each ball of shot weighing about 54 grains, that makes each projectile roughly equivalent to a .32 ACP bullet in terms of weight and caliber.

While multiple projectiles are in play when it comes to buckshot, this doesn’t mean that there will automatically be a dramatically wider spread of pellets. In fact, buckshot patterns generally remain quite tight within ranges of about 30 yards.

Certain loadings feature wad technology and plated projectiles that further aid in keeping the pattern tight during flight. Of course, the tightness of buckshot projectiles can also be influenced by a barrel’s choke. Buckshot is particularly effective for self-defense as each projectile will create its own dynamic wound channels upon impact and impart a high degree of energy transfer.

Shotgun Slugs

Slugs feature a single, solid projectile rather than multiple projectiles. This generally results in higher velocity than buckshot and a much greater effective range as well. Granted, when in the context of home defense, it is highly unlikely one would need to take any shots at extended ranges.

The benefit of the higher velocity possessed by slugs is evident in its effect on the target and its efficient fight-stopping capabilities. The velocity of slugs multiplied by their impressive mass results in a lot of energy and devastating terminal ballistics. Another potential advantage of slugs over buckshot is the fact you are only responsible for a single projectile as opposed to multiple.

That last point is worth some consideration when it comes to selecting home-defense 12-gauge ammo because you are legally and morally responsible for every projectile that you send out the barrel. Bullets can behave strangely, and 00 buck provides eight to nine times the likelihood that one of those lead balls ends up somewhere it shouldn’t.

The specific factors of one’s home environment, such as potential engagement distances, will impact whether or not slugs, buckshot or something else entirely will be the safest and smartest choice. Regardless of your selected load of 12-gauge ammo, it is prudent that you practice and familiarize yourself with how it behaves with your specific firearm.

Chokes and Patterns:

When it comes to shotguns, an important aspect of this class of firearm is the effect that chokes and bore tightness have on the patterning of projectiles. Many shotguns feature barrels with internal threads that accommodate a variety of chokes, making them tunable by the end user to match their chosen loads and needs.

Other shotguns, particularly base model defensive shotguns, feature bores that are fixed to a given choke size. For example, a Mossberg 590A1 features a fixed-cylinder bore while a Benelli Montefeltro comes with a set of Crio improved cylinder, modified, and full chokes.

The resultant spread sizes from various kinds of 12-gauge ammo. The patterns could be influenced by adjusting the choke as well.

There are a variety of chokes on the market that exist for both common and specialized uses. The most common chokes one will find when looking for a shotgun are cylinder, improved cylinder, modified and full chokes.

A cylinder choke will produce the widest dispersion of projectiles as the bore diameter is not tightened in any way. An improved cylinder choke tightens the bore, resulting in a tighter pattern than that of a standard cylinder bore. Full chokes feature the tightest bore diameter, conducive to ensuring that the projectiles maintain as concentrated of a pattern as possible during flight. Between improved cylinder and full chokes are modified chokes, providing a middle-ground option when it comes to pattern tightness.

Just like factoring ammunition options into one’s shotgun usage, being cognizant of a shotgun’s choke and bore diameter is an important step in optimizing your shotgun for its given task.

12-Gauge Ammo Shell Size

The most common size of shell when it comes to 12-gauge ammo is 2 ¾-inch, but other sizes exist as well. Excluding smaller mini shells which are mostly a novelty, 12-gauge ammo can also be found in 3-inch and 3 ½-inch shells. Naturally, the larger the shell size the more powerful it can potentially be.

These days, most 12-gauge shotguns come with at least a 3-inch chamber, but double-check before trying to jam anything larger than a standard 2 ¾-inch shell into it. To fire 3 ½-inch shells, one will usually have to go out of their way to find a shotgun with a chamber that can accommodate them. If the task at hand calls for the most powerful 12-gauge ammo available, such as self-defense in grizzly country, it may be worth tracking one down.
