jacket bullet
An essential requirement for the making of a FMJ bullet is that the base is closed after the core is tamped. A small amount of jacket material protrudes beyond the tamped lead core and is folded over the core. This is accomplished in two operations. Folding begins by coning the rear edge of the jacket; a base-finishing die flattens the base.
