A pellet is a non-spherical projectile designed to be fired from an air gun. Air gun pellets differ from bullets and shot used in firearms because of the pressures encountered: airguns operate at pressures as low as 50 atmospheres while firearms operate at thousands of atmospheres. Airguns generally use a slightly undersized projectile that is designed to obturate upon shooting so as to seal the bore, and engage the rifling. Firearms have sufficient pressure to force a slightly oversized bullet to fit the bore in order to form a tight seal. Since pellets may be shot through a smoothbore barrel, they are often designed to be inherently stable, much like the Foster slugs used in smoothbore shotguns
