Case, or canister shot appeared very early, and it usually consisted of a casing filled with lead musket balls. In many examples, where lead shot was used, the metal was alloyed with antimony to make the balls harder. Frequently, some wadding or waste was added to pack the shot tightly into the canister. Another similar design to case or canister shot was known as carcass shot, in which, the casing was filled with incendiary instead of antipersonnel materials..
