Underwater archaeologists in Sweden have determined that a chest in the wreck of a 15th-century warship held tools to make lead shots for early handguns. The finding hints at key changes in naval battles at the time.
The chest is in the wreck of the Gribshunden ("Griffin hound"), a Danish royal "floating castle" that sank in 1495 at an anchorage in southern Sweden after a fire attributed to the mishandling of gunpowder.
