Cartridge ammunition with at least a partially combustible propellant charge cartridge casing

Improved cartridge ammunition comprising a projectile having a tail section with flight stabilizing means and a propellant charge shell casing made of a combustible material, said casing having a neck and a rear portion for receiving said tail section, a metallic stump forming a bottom for said casing;

• said projectile is connected to the shell casing at said neck by means of first connection means and by means of second connection means between the tail section of the projectile and the metallic stump of the shell casing, said second connection means including a support element, the improvement comprising, a support region for said second connection means disposed inside said metallic stump of said shell casing and being axially spaced from the bottom of the said shell casing and from the bottom of the metallic stump, said support element coaxially extending between said tail section and the support region of said metallic stump of said shell casing and connecting said tail section to said metallic stump at said support region, said support element being made of a combustible material and providing a form-locking axially extending connection between said projectile and said metallic stump which inhibits a loosening of said projectile on loading, unloading, and reloading said ammunition unit, and assuring that a predetermined axial tensional force occurs in said support element between said tail section and said metallic stump due to gas pressure build-up at firing of the ammunition.
