Cartridge Option A is a joint development firms "Dynamite-Nobel" and "Heckler und Koch (Heckler & Koch)"For the G11 rifle. This sample test revealed a number of problems, in particular, excessive temperature rise of the charge and autoignition. The propellant charge consists of nitrocellulose with a curing agent to render it mechanically strong to form a parallelepiped 8h9h21 mm in size with a bullet in the front part and the recess for the capsule, and the intermediate or additional ignition charge.
In a modification of variant B (Cartridge 4,73MM x 33 DM11) propellant charge is pressed into a block size 8h8h32,8 mm. The bullet is fully recessed in charge, a cap made entirely of the explosive in the form of thin wafers without the metal shell, present in the previous sample. The charge of a new type, known as HITR (propelling charge high ignition temperature), withstands temperature 100 degrees above the autoignition charge nitrocellulose and mechanically stronger. Bullet classical form consists of a core of lead and the steel shell. When it hit the target does not form splinters and punches from mild steel plate thickness 6 mm at a distance 300 m and regular steel helmet at a distance 600 m.
