The .410 shotgun shell originates from the United Kingdom and was introduced in 1874 by the Eley Brothers. Like other shotshells, the .410 features a straight rimmed case which holds the loading’s shot. The .410 is noticeably narrower and slimmer than shotgun staples such as the 12 gauge and 20 gauge, giving it a distinct appearance. Due to its small size, the .410 shotshell holds a smaller payload and yields a tamer recoil impulse than its larger counterparts. The relatively light recoil of the .410 makes it a good shotgun round for first time shooters to become acquainted with as it will not punish them in the same way a 12 gauge would. This is particularly true for younger shooters and those with smaller frames. Like other shotgun rounds, the .410 can be found in birdshot, buckshot, slug, and other common types of shotgun loadings.
One will encounter a wide range of shotguns chambered in .410 bore. These firearms are available typically in the form of semi-automatic, double barrel, over-under, single shot, and pump action shotguns. One will encounter these firearms in various configurations and styles, typically optimized for specific use cases. Additionally, some revolvers and firearms in .45 Colt will be able to accept some types of .410 bore ammo.
.410 bore ammunition can be utilized in some specific firearms which are chambered for other calibers. Notably, some revolvers and other specific models of firearms chambered in .45 Colt are capable of accepting certain types of .410 ammo. A notable example of a firearm of this type is the Tarus Judge revolver. One should confer with their manual or ask their manufacturer if they are unsure about whether they can utilize .410 ammo in their firearm.
