How much lead was in a musket ball?

Musket balls were typically made of lead and usually weighed between 0.5 to 1 ounce (approximately 14 to 28 grams). The exact weight could vary based on the type of musket and its caliber. For example, a .69 caliber musket ball would weigh around 1 ounce, while smaller calibers would weigh less. The lead used in musket balls was often cast in molds to achieve uniformity.
