Abstract
A receptacle for the propelling charge for large caliber gun ammunition is combustible, and includes a barrel-protection coating which is applied directly to the interior surface of the receptacle. The coating is composed of a mixture of wax and titanium dioxide. In order to prevent the propelling charge powder in the receptacle from directly contacting the coating, the coating is covered with a thin metal foil, such as a thin lead foil.
