In artillery, a grapeshot is a type of ammunition that consists of a collection of smaller-caliber round shots packed tightly in a canvas bag and separated from the gunpowder charge by a metal wadding, rather than being a single solid projectile. When assembled, the shot resembled a cluster of grapes, hence the name. Grapeshot was used both on land and at sea. On firing, the canvas wrapping disintegrates and the contained balls scatter out from the muzzle, giving a ballistic effect similar to a giant shotgun.
