Abstract: A filler for disintegrating projectiles for training ammunition composed essentially of a screened low carbon, unalloyed steel powder produced by atomizing a corresponding steel melt to form a steel powder, subsequently subjecting the powder to a reducing soft annealing treatment at a temperature of between about 900.degree. and 1050.degree. C., subjecting the annealed product to a comminuting (e.g., beating, impact and scrubbing) process followed by screening, wherein the comminuting process lasts longer than 60 minutes and the screened powder has a grain size below 0.315 mm, an uncompressed or apparent density of between 3.9 and about 4.6 g.multidot.cm.sup.-3, and is compressible in such a manner that the resulting density of a pressed body to be incorporated into the disintegrating projectile lies between about 6.5 and 7.15 g/cm.sup.3.

Abstract: A disintegrating projectile for cartridged maneuver ammunition for an automatic weapon. The projectile includes a thin-walled and closed body of plastic-like material. The body includes a circularly cylindrical section which changes into a tapering hollow tip. A rotationally symmetrical, stiffening, one-piece plastic insert, is adapted to the inner wall of the hollow tip and extends longitudinally of the projectile between a rear circular delimitation and a front circular limitation. The insert has the shape of two cups and includes a circular disc serving as a common bottom of the cups which are arranged one behind the other in the longitudinal direction of the projectile. The rear cup has a side wall thickness that constantly increases from the rear circular delimitation to the adjacent face of the circular disc member and the front cup has a side wall thickness that constantly increases from the front circular delimitation to the adjacent face of the circular disc member.
