First-Time Guide to Buying Shotgun Shells

Buying shotgun shells for the first time can be surprisingly confusing. Walk into a sporting-goods store and you’ll see boxes marked with 12 gauge, 20 gauge, 2¾-inch, 3-inch, shot size, payload weight, FPS, lead, steel, bismuth, and tungsten. If you’re new to shotguns, figuring out what all those numbers mean can feel overwhelming.

The good news is that choosing the right shotgun shells becomes much easier once you understand the information printed on the box. The gauge must match your shotgun, the shell length must be compatible with the chamber, and the shot type and size should fit the game and regulations where you hunt.

This guide breaks down the basics so you can approach your first ammunition purchase with confidence.

How to Read a Shotgun Shell Box

A shotgun shell box contains most of the information you need to determine whether the ammunition is appropriate for your shotgun and intended use.

The most important specifications to understand are:

• Shotgun gauge
• Shell length
• Shot size
• Shot weight or payload
• Muzzle velocity
• Shot material

Let’s look at each one.

Shotgun Gauge

Shotgun gauge indicates the bore size of the shotgun and determines which ammunition is compatible with it.

The most common gauges you’ll encounter are 12 gauge and 20 gauge, although 10 gauge, 16 gauge, 28 gauge, and .410 bore are also used.

A 12-gauge shotgun requires 12-gauge ammunition, while a 20-gauge shotgun requires 20-gauge ammunition. Gauge is not interchangeable, so this should always be the first specification you verify when buying shotgun shells.

Why 20-Gauge Shells Are Usually Yellow

You may notice that many 20-gauge shotshells use yellow hulls, while 12-gauge shells are available in a much wider range of colors.

Yellow became an industry convention for 20 gauge decades ago, helping shooters distinguish the two common gauges and reduce the possibility of loading the wrong ammunition.

The color of a shell is not a substitute for reading the ammunition label. Always verify the gauge printed on the box and shell.

Shotgun Shell Length

The next specification is shotshell length, usually expressed in inches.

Common hunting loads include:

• 2¾-inch
• 3-inch
• 3½-inch

The shell length must be compatible with the chamber length of your shotgun.

You can usually find the chamber specification stamped on the barrel or listed in the owner’s manual. If you’re unsure, check the manufacturer’s documentation before purchasing or firing ammunition.

A critical rule for new shotgun owners is that a longer shell should not be fired simply because it physically fits into the chamber. For example, a 3-inch shell should not be fired in a shotgun chambered for 2¾-inch shells.

When you’re uncertain about chamber length or ammunition compatibility, stop and verify the specification with the owner’s manual or the firearm manufacturer.

Shot Size: What Do the Numbers Mean?

Shot size refers to the diameter of the individual pellets inside a shotshell.

This is one of the specifications that initially confused me the most because the larger the shot-size number, the smaller the pellet.

For example:

#6 shot is smaller than #4 shot, and #4 shot is smaller than #2 shot.

Shot size is selected according to the intended game, range, and load characteristics. There isn’t one universally “best” shot size because hunting situations vary.

As a broad starting point:

Shot Size	Common Applications
BB–#2	Waterfowl and larger game birds
#4–#6	Pheasant, chukar, Hungarian partridge and similar upland birds
#6–#9	Smaller upland birds and some clay-target applications

These are general examples rather than universal recommendations. Always consider the species, hunting distance, ammunition type, and local regulations.

Shot Weight or Payload

The number beside the shot size may indicate the payload weight, generally expressed in ounces.

For example, a shotshell labeled 1¼ oz #6 contains approximately 1¼ ounces of #6 shot.

Payload affects the number of pellets contained in the shell and can influence pattern density and recoil. Common hunting loads vary considerably in payload depending on gauge, shell length, shot material, and intended application.

More pellets aren’t automatically better. The useful question is how the entire load performs through your particular shotgun and choke at the distances you expect to shoot.

Understanding Shotgun Shell Velocity

You’ll also see a velocity specification expressed as FPS, or feet per second.

This represents the approximate muzzle velocity of the load. In general terms, higher-velocity ammunition gets the shot to the target more quickly, but velocity is only one part of overall shotshell performance.

Higher velocity can also increase perceived recoil.

You may occasionally encounter dram equivalent, or “Dram Eq,” on older or traditional shotshell packaging. It’s an older way of describing shotshell velocity and is less prominent on modern ammunition packaging.

Don’t assume that the highest FPS load is automatically the best choice. Pattern performance, recoil, shot material, payload, and the intended application all matter.

Lead vs. Non-Toxic Shot

One of the most important things to understand before buying shotgun ammunition is shot composition.

Shotshells may use lead or non-toxic alternatives such as:

• Steel
• Bismuth
• Tungsten-based shot

The correct choice depends on your shotgun, the species you’re hunting, and the regulations governing the area.

Waterfowl Hunting Requires Special Attention

Waterfowl hunters in the United States must use federally approved nontoxic shot. Regulations can also impose additional restrictions depending on the state, hunting area, or species.

Before purchasing ammunition, verify the current regulations for the exact place where you intend to hunt.

Don’t rely on an old hunting regulation booklet or assume that rules from one property apply somewhere else.

Can Every Shotgun Fire Steel Shot?

No.

This is particularly important with older shotguns and firearms with certain fixed-choke configurations.

Steel is harder than lead, and shotgun manufacturers may place specific restrictions on the use of steel or other non-toxic shot in particular firearms and choke systems.

Before purchasing steel shot, check:

1. Your shotgun’s owner’s manual
2. The barrel markings
3. The choke manufacturer’s specifications
4. The ammunition manufacturer’s recommendations
5. Applicable hunting regulations

If you’re uncertain whether your shotgun can safely handle a particular load, don’t guess. Consult the manufacturer or a qualified gunsmith.

Choosing Shotgun Shells for Your First Hunt

Once you understand the numbers on the box, choosing ammunition becomes much more straightforward.

Start with the shotgun rather than the game.

First, confirm the gauge. Your ammunition must match the gauge of your shotgun.

Second, verify chamber length. Make sure the shell length is approved for your shotgun.

Third, determine the required shot material. Check whether your hunting location requires non-toxic ammunition.

Fourth, select an appropriate shot size. Match the load to the species and expected shooting distance.

Finally, consider payload and velocity. These specifications affect pattern density, recoil, and overall shooting characteristics.

If possible, pattern your shotgun with the exact choke and ammunition combination you intend to hunt with. A shotshell that performs exceptionally well in one shotgun isn’t guaranteed to produce the same pattern in another.

Common First-Time Shotgun Shell Buying Mistakes

New shotgun owners can avoid many problems simply by slowing down at the ammunition counter.

Buying the Wrong Gauge

Never rely solely on shell color or appearance. Read the gauge printed on the ammunition box and confirm that it matches your shotgun.

Ignoring Chamber Length

A shell that appears to fit doesn’t necessarily mean it’s safe to fire. Verify the chamber specification before purchasing ammunition.

Choosing Shot Size Without Considering the Game

Shot size should be selected according to the intended application rather than simply choosing the largest or smallest pellets available.

Assuming More Velocity Is Always Better

A high-velocity load isn’t automatically the best load. Recoil, patterning, payload, and shooting conditions all matter.

Ignoring Local Regulations

Ammunition that is legal for one species or hunting area may not be legal for another. Check current regulations before your hunt.

Assuming Every Shotgun Handles Steel

Older shotguns and certain choke configurations may have restrictions on steel shot. Always verify compatibility first.

Shotgun Shell Buying Checklist

Before you leave the ammunition counter, make sure you can answer these questions:

• What gauge is my shotgun?
• What is the chamber length?
• What shell length am I buying?
• What shot size do I need?
• How much shot does the shell contain?
• What is the advertised velocity?
• Does the hunt require non-toxic shot?
• Is this shot material compatible with my shotgun and choke?
• Does this load comply with current local hunting regulations?

If you can answer those questions, you’ve already eliminated most of the confusion surrounding your first ammunition purchase.

Frequently Asked Questions

What shotgun shells should a beginner buy?

Start by identifying your shotgun’s gauge and chamber length, then select a load appropriate for your intended use. The correct ammunition depends on the firearm, game, shooting distance, shot material, and applicable regulations.

What is the difference between 12-gauge and 20-gauge shells?

The two gauges correspond to different shotgun bore sizes and require matching ammunition. Both are widely used for hunting and sporting applications, but the shotgun’s markings and owner’s manual should determine which ammunition you need.

What does 2¾-inch mean on a shotgun shell?

It refers to the shell length. The shell must be compatible with the shotgun’s chamber. Never assume that a longer shell is safe simply because it fits physically.

Is #4 shot bigger than #6 shot?

Yes. With traditional numbered shot sizes, the lower the number, the larger the pellet. Therefore, #4 shot is larger than #6 shot.

What does FPS mean on shotgun shells?

FPS means feet per second and refers to the approximate velocity of the shot as it leaves the barrel.

Can I use steel shot in my shotgun?

It depends on the shotgun, barrel, choke system, and manufacturer specifications. Check your owner’s manual and choke manufacturer’s guidance before using steel shot, particularly with older firearms.

Final Thoughts

Buying shotgun shells for the first time doesn’t have to be intimidating. Once you understand gauge, chamber length, shot size, payload, velocity, and shot material, the information on the ammunition box becomes much easier to read.

The most important rule is simple: verify compatibility before you buy or fire.

Match the gauge and shell length to your shotgun, choose shot appropriate for the intended use, check whether non-toxic ammunition is required, and confirm that the load is approved for your firearm and choke.

And if you’re standing at the gun counter wondering whether you’re the only person who doesn’t understand all those numbers, you’re not. Every experienced shotgunner was a first-time ammunition buyer once. The smart move isn’t pretending you know everything—it’s taking the time to verify what you need before you pull the trigger.
