A shell, in a modern military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell , contrasting with solid shells used for early rifled artillery, [ citation needed ] but "shell" has come to be unambiguous in a military context.
The projectile's motion in flight is known as its external ballistics, and its behavior upon impacting an object is known as its terminal ballistics. A bullet can be made of virtually anything (see below), but lead is the traditional material of choice because of its high density, malleability, ductility, and low cost of production.
A shotgun cartridge, shotshell, or shell is a type of rimmed, cylindrical (straight-walled) ammunition used specifically in shotguns. It is typically loaded with numerous small, spherical sub-projectiles called shot. Shotguns typically use a smoothbore barrel with a tapered constriction at the muzzle to regulate the extent of scattering.

The Pentagon recommended providing the white phosphorus shells to Ukraine as part of several aid packages, including a recent one, as a Presidential Drawdown Authority, according to the officials.
The usual nomenclature of ammunition indicates the diameter of projectile and the length of the cartridge that holds it; for example, 20×102 mm is a 20 mm projectile in a 102 mm long case. Though this designation is often assumed to be unique, this is not always the case, e.g. there are three different 20×110 mm types which are not compatible.
