There’s no doubt that the 12-gauge is the most popular shotgun in the United States. It is extremely versatile, and can handle a wide range of payloads for hunting anything North America has to offer. Furthermore, the 12 gauge is the de facto choice of military and law enforcement for all their tactical shotgun needs.

There is little question that 12 gauge shells are extremely powerful. But sadly, all those ballistic capabilities come at the cost of savage recoil that some shooters simply can’t handle effectively.

For those who need something with a little less recoil – but still plenty of stopping power – then 20 gauge ammo and .410 shotgun shells are both worth considering.

In this article we will compare the 20-gauge to the 410 and examine how each shotshell can best fit your needs as a hunter, concerned citizen, sporting clays shooter, or weekend plinker.

What’s the Difference Between 20 Gauge vs 410?

The difference between 20-gauge and 410 is this: the 20-gauge shotshell is larger, and carries a heavier powder charge and payload of shot compared to the 410.

20 Gauge vs 410: Understanding Shotgun Gauges

If you’re familiar with shotguns, you know that a lower gauge means a bigger shell. If you’re new to shotguns or firearms in general, this can be a confusing concept to grasp.

Handgun and rifle calibers are defined by their internal bore diameter. For example, a .40 caliber handgun has 0.40 inch diameter bore. An AR-15 barrel has a caliber of 0.224 inches, which is also the diameter if the 5.56 NATO bullet it's designed for. In essence, the larger its caliber, the wider the bullet a cartridge fires.

Shotgun gauges, however, are determined by a more archaic system.

Imagine you have 1 pound of lead. You divide it into 12 balls of equal size. You place one of those balls inside a 12-gauge shotgun's barrel. It is a perfect fit, by design. Likewise, dividing 1 pound of lead into 20 identical balls yields spheres with the same diameter as the bore of a 20-gauge shotgun. In essense, an X-gauge shotgun has a bore equal in diameter to a 1/X-pound lead ball.

The .410 Bore is unique among shotguns, as it abides by the rifle/handgun convention for measuring bore diameter. True to its name, its bore is 0.410 inches in diameter. If the .410 Bore were named by the alternative system, then it would be know as the "67.5-gauge."

A Special Note on 20-Gauge Shells: Yellow Is the New Black

If you’re new to shotguns, then you might not be aware that all 20-gauge shotgun shells are colored yellow.

This is to ensure that a shooter does not mistakenly load a 20-gauge shell into a 12-gauge shotgun. Were that to happen, then the 20-gauge shell could fall into the barrel and hang there. If the shooter were then to load a 12-gauge shell on top of the original 20-gauge shell., the resulting "double-ignition" would be violent enough to blow up the shotgun.

For this reason, manufacturers color all 20-gauge loads yellow to make them easily distinguishable from other rounds. They aren't legally obligated to do this. It is simply a universally respected safety protocol.

Recoil

Shop 410 Ammo

A 410 shotshell has incredibly light recoil compared to a 20-gauge shell.

Recoil is an important consideration when purchasing a new shotgun, as a round with heavy recoil will be more difficult to control and will slow your rate of follow-up shots.

Recoil is wholly determined by four factors: muzzle velocity (measured in feet per second, or fps), powder charge weight, bullet (or shot column) weight, and firearm weight. In the case of a shotshell, the weight of the wad also contributes to recoil energy.

It’s always preferable to compare free recoil on firearms of similar weight. However, this is not realistic when comparing 20-gauge vs 410, as 20-gauge guns are typically heavier. A heavier gun will soak up more recoil, whereas a lighter gun will be easier to carry in the field.

410 bore shotguns are typically lighter than 20-gauge guns, which makes the 410 is an excellent training shotgun for a 6- to 12-year-old. A Mossberg 500 youth model 410 shotgun weighs only 5 pounds. In comparison, a 20-gauge shotgun like a Remington 870 weighs around 6.5 to 7 pounds.

Projectile weight and muzzle velocity both vary considerably across different types of ammunition. However, in general, the 410 has around half to one-third the recoil of 20-gauge shells. This is due to the 410 firing lighter payloads with smaller powder charges. Typical free recoil for a 410 is around 7-10 ft-lbs, compared to 20-30 ft-lbs for a 20 ga. Felt recoil can be mitigated with the use of a good recoil pad, as well as by choosing a heavier shotgun (or making an existing shotgun heavier somehow).

Accuracy/Pattern Density

To understand pattern density, it’s important to understand how a shotgun shell works.

Shop 20 Gauge Ammo

A shotgun shell, or shotshell, is a plastic hull with a primer at the bottom. Inside the hull is a powder charge. On top of that is a plastic cup known as a “wad” which holds the projectiles known as “shot”, which are essentially just lead (or steel) balls.

Different shot sizes are preferable for different applications.

For self-defense you would want to use something larger like 00 buckshot (pronounced “double aught”). If you’re hunting something smaller, like grouse or pheasant, a smaller option like #8 shot would be ideal.

One common misconception is that once the shot exits the barrel, it quickly disperses into a wide pattern. In fact, shot travels in a much narrower cluster than what Hollywood movies might have you believe.

Numerous factors affect how shot disperses, such as minor imperfections on the surface of the shot pellets, muzzle velocity, and "stringing."

Stringing is a process whereby shot at the top of the column deforms very little during ignition, whereas shot at the bottom of the column deforms substantially under the the weight of all the shot on top of it. This means that buckshot at the top of the column will reach the target faster (because it’s more aerodynamic) than the shot at the bottom of the column.

The width of dispersion of shot when it reaches its target is referred to as "pattern density." If pattern density is too wide, it’s possible to miss a smaller bird, like a quail, at range. Conversely, if pattern density is too tight, it will make it harder for the shooter to score hits.

One other factor that affects pattern density is the type of choke being used in the shotgun barrel. A choke typically screws into the barrel where it acts as a forcing cone, constricting the shot column so as to determine how narrowly it will pattern at range.

Shop 410 Ammo

As the 20-gauge has a wider bore diameter than the 410, it can fit more shot into its wad. This means that it will have a denser pattern than 410, which makes hitting moving targets with it easier.

Since the 410 shell carries less shot, most 410 bore shotguns are installed with full chokes at the factory. A full choke helps concentrate what little shot the 410 can launch and creates an extremely tight pattern at close range. Despite having this advantage, the 410's lower quantity of shot still gives it a hard time hitting moving targets like upland birds at distances over 30 yards.

Hunting

Although the 410 is more than capable of taking whitetail with slugs, many hunters prefer the denser shot pattern of 20-gauge loads when hunting upland game and waterfowl.

When discussing hunting, many hunters separate the discussion between 410 vs 20 gauge into bird vs deer hunting. This is because the hunter has different requirements for either pursuit.

For hunting deer and similarly sized game, both the 410 and the 20 gauge will get the job done when firing slugs. The low recoil of the 410 is particularly appealing to beginners or young hunters who are venturing into the woods for the first time. (Make sure to follow all state and local laws, as some areas prohibit the use of 410 for hunting deer.)

If your state allows hunting with buckshot, then the 20-gauge is the better choice. This is due to the 20 gauge’s larger size and higher capacity for shot. More shot means more chances to hit the vital organs and ethically claim the deer.

The same holds true for waterfowl and upland game hunting. The higher pattern density of 20-gauge shells make them the better option. The 410 not only carries less shot, but it also has a tighter pattern that quickly disperses at range. This makes it difficult to score killing shots on fast-moving upland birds like pheasant and grouse.

Shop 20 Gauge Ammo

The risk of wounding a bird instead of quickly killing it is higher with the 410. This is again due to the low shot count in its smaller hulls. With less shot there is a lower chance for a killing hit, even with birdshot. This makes the 20-gauge a better choice for upland game.

For waterfowl and turkey, most hunters prefer a 12-gauge shotgun. They want the extra power the shell offers while bagging larger birds. However, if you had to choose between 20 gauge vs 410 for geese, ducks, and turkey, the 20-gauge is the clear choice.

Don't forget to stock up on ammo! Check out our Fiocchi 20-gauge ammo page for more options. For hunters who go through significant quantities during the season, purchasing bulk 20 gauge ammo ensures you're always prepared while maximizing value.

Although the 410 is not the best choice for birds, it is an excellent option for pest control. Rabbits, squirrels, snakes, coyotes, and raccoons all fall against the power of the 410. Furthermore, the low recoil of the 410 makes it easy to line up follow-up shots should you need any.

Within 20-30 yards, the 410 is an excellent varmint shell. The 20-gauge might be a little bit overkill on small game at the same range.

Self-Defense/Home Defense

When it comes to home defense, it’s hard to beat a shotgun. Although some shooters contest that a handgun is the better choice, it simply does not compare to the sheer power a shotgun offers.

For home defense, it is inadvisable to use rifled slugs, which are highly likely to over-penetrate (and therefore jeopardize bystanders). Buckshot is what you want loaded in your self-defense shotgun.

There is some scholarly debate amongst ballisticians as to which type buckshot is the best option for home defense. Many swear by 00 buckshot, as it is considered the gold standard for self-defense. Many others claim that #1 or #2 buckshot is more than sufficient for any home defense situation.

If you’re unfamiliar with buckshot sizes, here is a chart explaining them.

As you can see, the difference between a 00 buckshot and #1 buckshot pellet is 0.03” in diameter. Despite this apparently small difference, a pellet of 00 buck weighs almost one-third more than a #1 pellet: the reason why it strikes so much harder, and has a higher risk of over-penetration.

Which shotgun would be better for home defense? A 20-gauge? Or a 410?

Many shooters like the feel of a 20-gauge shotgun for home defense. They feel that it is a good compromise between recoil and pattern density. On the other hand, some like the even lower recoil of the 410 shell, and feel they are more accurate with it.

For close-range engagements – such as those in a home – it won’t make much difference which shotgun you choose. Both will be more than effective in defending your life and the lives of your friends and/or family members. A 20-gauge will offer slightly deeper penetration than a 410, but it’s unlikely any would-be home invader could tell the difference.

Make sure to load up on quality buckshot (NOT birdshot, target loads, or slugs) for home defense, and you should be more than adequately prepared to take on any threat that enters your home.

Ammo and Shotgun Cost/Availability

The beautiful thing about shotguns is their versatility. You have so many options – single shot, side by side, over/under, pump-action, and even semi-auto – that the world is your oyster when it comes to shotguns.

Shop 410 Ammo

Entry-level pump-action models are typically inexpensive compared to most centerfire rifles and handguns. You can easily pick up a Remington 870 or Mossberg 500 for around $400 new in box (at the time of writing).

This does not mean that all shotguns are so affordable. If you’re looking to get into sporting clays, skeet, or trap shooting, most competition-ready shotguns, like a Browning Citori, will command over a thousand dollars.

The 410 is special because it can safely chamber in a 45 Long Colt cylinder. This led to the creation of the Smith & Wesson Governor and the Taurus Judge: two revolvers that can fire 45 LC and 410.

In terms of ammo availability, 20 gauge will be easier to find. It is also less expensive than 410.

The 20-gauge is the second most popular shotgun shell on the market, only outdone by the 12. This popularity means that the 20 gauge ammo will be easier to locate.

Inexpensive 20-gauge target loads from Winchester, Remington, Federal, and Estate can cost as low as $0.40/shell, while premium game loads start around $1/shell and go up from there. On the other hand, 410 target loads typically start at around $1/shell, and premium hunting loads go for $1.50/shell or more.

Reloading

Reloading shotgun shells is something that many shooters enjoy doing. However, as shotshells are relatively inexpensive, most reloaders do not bother reloading used hulls.

Shop 20 Gauge Ammo

The cost savings for reloading shotgun shells is so low that only high-volume shooters ever worry about doing it, as it is usually cheaper just to buy new factory shotgun ammo. However, if you love the idea of optimizing your shotgun ammo, then there’s nothing stopping you from loading your own shotshells.

Please note that shotshell reloading requires a specialized press that cannot be used for centerfire rifle or handgun reloading.

A Brief History of the Shotgun Shell

In their infancy, most firearms could fire a single projectile or multiple as they all had smooth bores.

With the introduction of rifling during the mid-16th century, rifles and shotguns became two separate entities with different purposes. At this time, shotguns were mostly used for bird hunting, but also saw use in law enforcement and protection details.

The first shotgun shell was introduced by French gunsmith Casimir Lefaucheux in 1836. Most early shotgun shells were made entirely of brass, as paper cartridges were unreliable and couldn’t be reloaded.

It wasn’t until 1960 when Remington introduced the plastic shotgun hull that is used today.

Final Shots: 20 Gauge vs 410

The 410 vs 20 gauge discussion boils down to a compromise between low recoil vs power and pattern density.

The 20-gauge is the second most popular shotgun in the United States, only trailing behind the mighty 12-gauge. The 20-gauge shotshell offers lower recoil than a 12-gauge and still delivers more than enough stopping power to take down most upland game and deer.

The 410 has extremely light recoil, and is most often chambered in youth model shotguns (though many adult shotguns are also available in 410). It is often considered a "beginner shotshell" that young shooters can use to learn shotgun handling skills before graduating to a larger shell.

The major issue with the 410 is its limited range and low payload. Since the 410 is smaller, it cannot carry as much shot as a 20-gauge, and its weaker powder charge reduces the killing potential of the small amount of shot it does fire.

The majority of shooters and hunters opt for the 20-gauge shotgun, as it offers good shot pattern density with moderate recoil that can be easily mitigated with a recoil pad. The 410 is great for young shooters, those who are recoil sensitive, and hunters who want the added challenge of shooting with a self-imposed handicap.
