Abstract: The invention relates to a method for reducing an imbalance of a projectile shell. The projectile shell has a body (1) which has a recess (4). By this recess (4), the body is provided with an inner wall (2) and an outer wall (3). In addition, a mouth hole (6) is provided, which is connected to the recess (4). A central axis (5) is now calculated from the outer geometrical shape of the projectile shell and a measurement is then performed to ascertain an imbalance of the projectile shell. On the basis of the measured imbalance, modified axis (8) is then calculated in relation to the central axis (5), and the body (1) is rotated about the modified axis (8) on the basis of the calculated modified axis (8). As the body (1) is rotated in this way, the projectile shell is machined to eliminate the imbalance as far as possible.

Abstract: The invention relates to a test and/or practice ammunition having at least one projectile with a projectile head and a fin which can be found at the end of the projectile for example or a projectile with a projectile base and a projectile ogive. A cartridge shell is used to receive a drive and has a shell base, wherein an interface is attached in or on the shell base. The test and/or practice ammunition is characterized by a programmable fuze which is arranged in the projectile head or the projectile ogive. The projectile head/projectile ogive is equipped with at least one fuze amplifier and an electronic fuze system and optionally a separating charge.
