Identifying musket balls and shot

Lead spheres that map skirmishes, hunts, and target practice.

Cast lead balls served firearms from the 16th to the mid-19th century. Diameter is the key fact: pistol balls run small (under ~12 mm), musket balls larger (~15–19 mm). A flattened or mushroomed ball was fired into something; a pristine one with a visible casting sprue or mould seam was dropped unfired.

Look for the sprue stub where the ball was cut from its mould, seam lines from two-part moulds, and teeth or ramrod marks. Smaller uniform pellets in quantity are shotgun or bird shot and usually recent; oddly faceted lumps may be case shot or chewed by ploughing.

In numbers, musket balls sketch an event — record each findspot carefully rather than pooling them. Measure diameter with calipers, weigh them, and note deformation; distribution plus calibre is how battlefield archaeologists reconstruct a fight.
