What makes the .410 different
The .410 is the only common shotgun size named by bore diameter instead of gauge. Its bore is about .410 inches, which would be roughly a 67 gauge on the traditional scale. Our 12 gauge explainer covers why gauge and the .410 use different systems.
The small bore means a small payload, usually 1/2 to 11/16 oz of shot, compared with 1 to 1-1/4 oz for a typical 12 gauge field load. Fewer pellets means a thinner pattern, so the .410 rewards short shots and good aim. It's often called a beginner's gun because recoil is light, but many experienced shooters consider it an expert's gun because there's so little margin for error.
Shell lengths: 2-1/2 vs 3 inch
.410 shells come in two common lengths:
- 2-1/2 inch: the standard for skeet and target shooting, usually 1/2 oz of shot.
- 3 inch: more payload, often 11/16 oz, for hunting.
Your gun's chamber length is usually stamped on the barrel. A 3-inch chamber can fire both lengths. A 2-1/2 inch chamber should never be fed 3-inch shells. When in doubt, check the barrel and the manual.
Best for turkey: TSS
For decades the .410 was considered too light for turkeys. Tungsten Super Shot changed that. TSS pellets are far denser than lead, so even tiny #9 pellets carry enough energy to penetrate at modest distances, and a .410 shell can hold hundreds of them.
TSS is a premium product, and it's expensive per shell. Buy a box to pattern, then buy your season's supply. Our turkey load guide compares TSS with lead and heavyweight loads in larger gauges.
Best for small game
Squirrels and rabbits are the .410's traditional job. A 3-inch shell with #6 shot balances pattern density and penetration; some hunters use #7½ for rabbits at very close range in thick cover.
Best for clays and practice
For skeet, informal clays and teaching, a 2-1/2 inch, 1/2 oz load of #8 or #9 is standard. These are the cheapest .410 shells to buy and the gentlest to shoot.
Ammunition Depot's .410 ammo page lists more target and field loads, plus slugs and home-defense shells.
.410 revolvers and defense loads
Revolvers like the Taurus Judge and Smith & Wesson Governor chamber .410 shells alongside .45 Colt. That's made .410 "defense" loads popular, such as Hornady's Critical Defense Triple Defense, which combines a slug with round balls.
A few cautions:
- Short revolver barrels and rifling change how shot patterns. Pattern any load at realistic distances before trusting it.
- Birdshot from a .410 revolver often lacks penetration for defense. Loads with buckshot or slugs are designed for that job.
- Check your revolver's cylinder length. Some accept only 2-1/2 inch shells; others accept 3-inch.
- Most defensive guidance favors a standard centerfire handgun or a larger-bore shotgun for home defense. Our home defense ammo guide covers the options.
Storage and safety tips
- Keep .410 shells separate from other gauges and from .45 Colt cartridges if you own a revolver that fires both.
- Store shells in a cool, dry place; paper and plastic hulls both dislike moisture.
- TSS is expensive; keep it in a labeled box so it doesn't get mixed with practice ammo.
- Pattern every new hunting load. A .410 leaves very little margin.
Choosing a choke for .410
Choke choice matters more in .410 than in bigger gauges, because the pattern is already thin.
- Skeet and close targets: a more open choke spreads the small payload quickly for close, fast targets.
- Squirrels and rabbits: Modified or Full helps keep the pattern dense enough at typical small-game distances.
- Turkey with TSS: use a turkey choke the maker approves for TSS or tungsten shot, and pattern it carefully. Some chokes aren't rated for very hard shot.
Many .410 shotguns have fixed chokes. Check the barrel markings or the manual so you know what you're working with. Our choke and ammo pairing guide explains how constriction affects patterns.
Patterning a .410
Pattern every hunting load before the season. Hang a large sheet of paper at your expected shot distance, fire from a rest, and count hits inside a circle. For turkey, check how many pellets land in the head and neck area. For small game, look for gaps that a squirrel's vitals could slip through. If the pattern looks thin, shorten your shot distance or try a different load or choke.
Cost per shot
.410 target shells are inexpensive, but .410 hunting shells, especially TSS, can cost more per shell than many 12 gauge loads. If budget matters, practice with cheap target loads and save the expensive shells for the hunt itself.
Who the .410 suits best
The .410 makes the most sense for shooters who value a light, low-recoil gun and are willing to keep shots short: young hunters under close supervision, small-framed adults, hunters who walk a long way for squirrels, and experienced shotgunners who enjoy the challenge. If you want the most forgiving pattern for clays or birds, a 20 gauge with light loads usually hits more targets with similar comfort. Our 20 gauge ammo guide covers that option.
Whatever you choose, keep .410 shells in their original boxes so the shell length, payload and shot size stay with them.
Frequently asked questions
Is .410 good for turkey hunting?
With modern TSS loads, many hunters use it successfully at close range. Pattern it carefully and keep shots well inside its effective distance.
What shot size is best for squirrels in .410?
#6 is a common choice in a 3-inch shell. Some hunters use #7½ for very close shots or rabbits in thick cover.
Can I shoot 3-inch .410 shells in a 2-1/2 inch chamber?
No. Never fire a shell longer than your chamber. Check the stamp on the barrel or your manual.
Is .410 good for beginners?
It has light recoil, which helps. But its small pattern makes hitting harder. Many instructors start new shooters on a 20 gauge with light loads instead.
What is a .410 in gauge?
It's named by bore diameter, about .410 inches. On the gauge scale it would be roughly a 67 gauge.
