Cal. 4.73 x 33 Caseless
There is probably no other weapon concept in modern times that has been more ambitious in scope and breadth than the G11 project. You would expect no other firearms manufacturer to even think about designing something in such uncharted territory as caseless ammunition in a military rifle with select fire capability. Who else but Heckler & Koch is up to the task?
It should be noted that not all of the prototypes have been photographed. That is why the prototype numbers are not consecutive.
First prototypes of the caseless G11 ammunition from Dynamit Nobel. Caliber 4.3mm.
Prototype caseless rounds, caliber 4.9 mm.
Prototype rounds 4.7mm x 2, for use with G11 prototype number 6.
With the HITP cartridge below, one can see the difference visually in the composition of the propellant, and the pace of development that was taking place.
The G11K2 with stripper clip and magazine of 4.73mm x 33 DM11 caseless cartridges. The K2 allowed two additional magazines to be placed on top of the gun, with the center magazine actually feeding the mechanism. The others were spares.
One of the selling points about the G11 and caseless technology was its comparison to conventional weapon systems. For the German Bundeswehr, still fielding the G3, the comparison should be obvious. For American purposes the M16 was included for comparison, since the G11 was HK's entry into the Advanced Combat Rifle program in the early 1990s. The ACR program eventually ended with the U.S. government choosing improvements on the M16 system for the forseeable future.
