ABSTRACT OF THE DISCLOSURE The present invention relates to a filler for disinte- grating projectiles used as training ammunition and a process for the production of same. Disintegrating projectiles of this kind have to fulfill the various safety conditions in a reliable manner. Using the filler according to the present invention, and/ or compacts produced from these, the danger area in front of the muzzle has been reduced considerably. Steel powder that is sieved off after a hammering and tumbling treatment lasting for longer than 60 minutes has a dust-free grain fraction of under 0.315 mm and a filling density between approximately 3.9 and 4.6 g.cm-3 and can be compacted such that the resulting density of a compact to be incorporated in a disintegrating projectile lies between approximately 6.5 and 7.15 g.cm-3, depending on the height and the shape of the compact.
