A shotgun shell or shotshell is a self-contained cartridge loaded with lead shot or a shotgun slug which is designed to be fired from a shotgun.
Most shotgun shells are designed to be fired from a smoothbore barrel, but dedicated shotguns with rifled barrels may take a number of different rounds. A rifled barrel will increase the accuracy of slugs, but makes it unsuitable for firing shot, as the shot wears down the rifling and the rifling causes the shot to form a hollow "O" shape in flight. Non-lethal shotgun ammunition is available in the form of slugs made of low-density material, such as rubber. See shotgun specialty ammunition for more information.
Famous quotes containing the word shell:
“I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.”
—Isaac Newton (16421727)
