This article details the caseless ammunition used in many iterations of the Heckler & Koch G11 assault rifle.
Propellant Body[]
The caseless ammunition uses a body made of solid propellant. In the older versions of the cartridge used nitrocellulose (NC) powder compressed into a solid mass. Later on, the material was changed to a High Ignition Temperature Propellant (HITP) based on HMX explosive compound.
4.3×21mm[]
The 4.3×21mm is the first generation of the G11 caseless ammunition, used in the first few prototypes of the G11 rifle. It has a body of compressed nitrocellulose powder with the projectile sticking out the front of it. The primer is not placed on the bottom side of the propellant body, but rather on the side of it.
4.9×20.4mm[]
The 4.9×20.4mm is one of several calibers of the G11's caseless ammunition. Like the previous calibers before it, it had a compressed nitrocellulose propellant body with a side primer.
Some rounds had materials wrapped around the propellant body in attempts to resolve the cook-off problems. Some had paper, while others used aluminum foil.
4.75×21mm[]
The 4.75×21mm is one of several calibers of the G11's caseless ammunition. It is the first caliber where HITP is used for the propellant body. It was developed for the 1978 NATO trials.
