The Definition of Sabot
An oversized, lightweight housing that allows a sub-calibre projectile to be fired in a larger-diameter bore, usually in the interest of increased velocity.
The sabot falls away from the actual projectile upon exiting the muzzle.
For example, a hunter could use his .30-30 deer rifle to shoot small game with .22 centerfire bullets.
