Abstract
The present invention falls in the field of propellant charges for ballistic ammunitions which have combustible or a non-combustible casing. According to the invention, the ammunition is constituted by a casing 2 placed around a shell 1 and closed by a portion 3 which carries the primer 4. The casing contains a mixed charge constituted on one hand by fragmentable balls 5 and on the other hand, by grains 6 of propellant powder. The balls 5 are constituted by agglomerated propellant powder. The charges according to the invention may be prepared on an industrial scale very easily and in a very reproducible manner and they permit an appreciable increase of the coefficient of filling of the casing.
