CASE-SHOT: Also known as spherical case-shot. Similar to the common shell except that the walls of the projectile were thinner. In both spherical and rifled projectiles, the bursting charge was usually located in a thin tin or iron container and placed in the center of the internal cavity. The case-shot was placed around this container. The cavity was usually filled with lead or iron balls in a sulphur or pitch matrix. The small bursting charge of black powder was designed to disperse the case-shot balls in a cone-shaped pattern. The concept was to give the same effects of canister, but at much longer ranges. Spherical case-shot was invented by an Englishman named Lieutenant Henry Shrapnel of the Royal Artillery in 1784. For an example of a cross-section of a case-shot projectile.
