Abstract
The invention relates to a projectile (5) with a frangible material, for short-range ammunition. To prevent any significant losses of precision and prevent the internal ballistic loading from being so great that it leads to the destruction of the projectile, it is suggested according to the invention that the projectile (5) consists of a shell (4) made of brass, the shell (4) has, seen in the direction of flight, a front cylindrical receiving space (4a) and a rear cylindrical receiving space (4b), the two receiving spaces (4a, 4b) are arranged coaxially with the longitudinal axis (15) of the projectile and are separated from each other by a partition wall (16), the partition wall (16) forms the floor (18) of the front receiving space (4a), and a core (1) of a frangible material is inserted in the front receiving space (4a), the tip (17) of the core (1) protrudes out of the front receiving space (4a), and at least one predetermined breaking point (2), running around the circumference of the shell (4), is formed in the shell (4) in the region of the partition wall (16).
