An inactive aerial ballistic element for exercises includes a main hollow body and a ballast element. The main hollow body has an ogive, disposed in the front portion, and a closure bottom, disposed in the rear portion. The ballast element is disposed in the main hollow body, and gives to the inactive ballistic element the same ballistic features of active ballistic elements. The ballast element includes at least a monolithic body coaxially disposed in the main hollow body of the inactive ballistic element and extending at least between the ogive and the closure bottom. The ogive includes the end of the monolithic body, which protrudes from the main hollow body of the inactive ballistic element.
