Munition container

There is disclosed a munition container that stores a munition in a sealed environment such that the seal need not be broken until the munition is ejected from the container into the breech of a gun. The benefits of this are that the munition is protected from the external environment for longer and that the loading operation is accelerated. To facilitate this, the container is provided with a lid & piston which forms part of the seal. The piston may, upon urging by e.g. a ram, slide within the container and outwards into the aligned breech.
