.410 bore

A .410 bore shotgun loaded with shot shells is well suited for small game hunting and pest control.

Lancaster's pattern centerfire and pinfire .410 shot cartridges first appeared in Eley Brothers Ltd. flysheets in 1857.

Shotguns in .410 loaded with shot shells are well suited for small game hunting and pest control.

It originally sold for $89.95 and was marketed as a general-purpose utility shotgun "perfect" for "fishing — hunting — camping — back packing — survival — home defense — truck or Jeep gun".

The military also lists an aluminum .410 3-inch (76 mm) shell, with a rifle primer, as standard issue under the ammunition inventory name M-35.

The civilian version Springfield Armory M6 Scout has a .22 rimfire or .22 Hornet over a .410 bore shotgun barrel.

The original M6 has a 14-inch (360 mm) barrel, the same length as the stock, and folds in half for storage, making a compact package.

The Thompson Center Arms Contender pistols are commonly encountered with a special .45 Colt/.410 bore barrel.

[13] Also, Taurus, Magnum Research, and Smith & Wesson offer revolvers with extended cylinders, long enough to hold .410 shells as well.

The Smith & Wesson Governor is a double-action revolver also capable of firing .45 Colt as well as .45 ACP cartridges with the aid of moon clips.

Shotgun gauge is determined by the weight of a round lead ball that is sized to fit into its barrel.
