.410 Bore Ammo for Sale — Birdshot, Slugs & Defense Loads

410 Ga Ammo

The .410 bore (technically a caliber, not a true gauge) is the smallest common shotgun shell — light-recoiling, lightly payloaded, and equally at home in youth shotguns, small game pursuits, and the popular handgun-shotgun crossover platforms like the Taurus Judge and Smith & Wesson Governor. Impact Guns carries .410 birdshot, slugs, and specialty defensive loads.

What the .410 Bore Is — and Isn’t

The .410 is the only common shotgun shell named by caliber (.410 inch bore diameter) rather than gauge. Its shot payload runs roughly ½ ounce in 2-1/2” shells, ¾ ounce in 3” magnum shells — about a quarter to a third the payload of 12 gauge. The .410 is light-duty: ideal for new and youth shooters, small game and pest control, and as the chambering for shot-firing handguns like the Taurus Judge. It is not a substitute for 12 or 20 gauge at typical hunting ranges.

Birdshot for Small Game

.410 birdshot in #7½ or #8 handles squirrels, rabbits, doves, and quail at modest ranges — typically inside 25 yards for ethical kills. #6 covers pheasant and grouse for skilled wing shooters who close the range. The small payload demands precise shot placement; .410 rewards shooters who can call their shots and isn’t forgiving of the same patterning errors a 12 gauge would absorb.

.410 Slugs

.410 slugs fire a single projectile (typically .40 caliber, ~93 grain) at moderate velocity — effective on small game and at very short ranges on deer-sized animals, though most jurisdictions don’t consider .410 adequate for deer hunting. The more practical role for .410 slugs is the Taurus Judge / S&W Governor revolver platform, where slugs provide rifled-bullet performance from the shotgun-revolver hybrid.

.410 for Personal Defense and the Judge

The Taurus Judge and Smith & Wesson Governor accept .410 shells and .45 Colt cartridges interchangeably — producing a category of dedicated defensive .410 ammunition. Federal Premium Personal Defense and Hornady Critical Defense both produce .410 loads specifically designed for these revolvers, using a combination of plated lead disks and balls to maximize close-range stopping power. These specialty loads cost more than birdshot and are tuned for short barrels and personal defense distances.

2-1/2” vs. 3” Magnum

.410 ships in 2-1/2” and 3” magnum shell lengths. The 3” magnum adds payload meaningfully — about 50% more shot — and is the standard for serious .410 hunting use. The 2-1/2” suits ultralight target use and revolver-style platforms with shorter chambers. Most modern .410 shotguns accept both; some older guns and the original Taurus Judge are 2-1/2” only. Verify chamber length before buying 3” shells.

Frequently Asked Questions

Is .410 good for home defense?
For dedicated home defense, 20 gauge or 12 gauge buckshot is more effective. The .410 from a Judge-pattern revolver can provide some defensive capability with specialty loads, but the payload limitations are real. A .410 shotgun is acceptable for shooters who can’t handle larger gauges; otherwise, larger gauges remain preferred.

What can I hunt with a .410?
.410 is well suited for squirrels, rabbits, doves, quail at modest ranges, and small predators. It’s legal for turkey in some jurisdictions with TSS (tungsten super shot) loads, but standard lead .410 turkey loads are marginal. Most hunters consider .410 inadequate for deer.

Can I shoot .410 in my 12 gauge shotgun?
No — .410 shells do not fit 12 gauge chambers and would be unsafe even if forced. Each gauge has its own specific chamber dimensions. The exception is over-under and combination guns specifically chambered for .410 in one barrel; verify barrel markings before loading.
