Brass–the part of the shotshell containing the primer.
Rifling–spiral-like casts on the inside of some shotgun barrels, these are paired with saboted slugs to increase the slug’s rotation as it leaves the barrel.
Sabot–a plastic shell around some shotgun shells, which give the projectile a degree of spin as it leaves the barrel.
Slug–a single projectile round in a shotgun shell, used for hunting larger game.
Wadding or Wad–this prevents the shot and powder from mixing, and provides a seal to keep gas from blowing through the shot instead of pushing it forward.
These range in size and number according to their usage.
Shot–the pellets inside some shotgun pellets.
Bore–the interior diameter of a tube or cylinder, in this case, the inside of the shotgun barrel.
Don’t worry, we’ll define each of them for you so you’ll have a better understanding of shotgun shells and how all the parts work together. Okay, we threw a bunch of unfamiliar terms at you in the above description of a shotgun shell. The brass base of the shell is thick enough to hold the primer, which is longer than those used for rifle and pistol ammunition. Starting at the brass, the layers of a shotgun shell are brass, propellant, over-powder wad, shot wad, shot pellets (or slug), over-shot wad, and top crimping. Shotguns are also capable of firing a single projectile, called a ‘ slug’.Ī shotgun shell is cased in plastic with a brass base containing the primer. A shotgun shell is a “a self-contained cartridge typically loaded with multiple metallic ‘shot’, which are small, generally spherical projectiles.”
