A method of making a bullet includes metal injection molding a bullet jacket or preform, and forming the jacket or preform into a bullet.

Development of different inorganic materials, having the capacity to generate visible colors when excited in the infrared region, which can be used to determine the origin of explosives, fuses and ammunition, even after detonation, and in weapons and metal projectiles, thus serving as a safety marking tool thereof. The following were developed: LaNbO.sub.4 (called Mark1), BiVO.sub.4, Sr.sub.3V.sub.2O.sub.8 and YNbO.sub.4 (called Mark2), doped with different rare earth ions (erbium, ytterbium, holmium and thulium). The markers were physically inserted inside the explosives and in the gunpowder and by carburizing and forging in steel or metal alloy, with which the weapon or metal projectile is manufactured. The parameter used to demonstrate the presence of the markers in the products, after detonation or scraping of the weapon, was the verification of the color identity of the marker fluorescence, before and after, via laser in the infrared region.

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.

An ammunition reloading system is configured to be operatively coupled with an ammunition reloading press to enable automated operation of the press. The reloading system includes a motor and a power transmission assembly that enables rotational power in a single direction from the motor to drive the ammunition reloading press. A controller is communicatively coupled to the motor and to one or more press position sensors to determine a position of the press within a press stroke cycle and increase or decrease the speed of the motor accordingly.

An automatic ammunition reloading system includes an actuation assembly in communication with a control system. The actuation assembly is joined to a reloading press by attaching to a control segment of the ammunition press so as to put the reloading press in operative relation with the actuation assembly. The control system receives input from one or more press position sensors to determine an actuation distance of the control lever for a full stroke of the reloading press. The control system controls operation of the actuation assembly so as to power the reloading press.
