Abstract: Apparatus for convenient and secure storage of firearm ammunition, especially shotshells, while permitting quick access to the shells for loading of the gun. In one preferred embodiment, the apparatus comprises a main storage compartment, capable of holding a full box of shotgun shells, having an extended shell loading tray. A removable snap fit lid fits atop the main storage compartment, and projecting lips on the rear wall of the main storage compartment fit into a channel on an accompanying base. The base may be mounted on a structure, for example the wall of a hunting blind. To use the apparatus, the main storage compartment can then be removed, inverted over a full box of shotgun shells, then turned over again together with the box of shells. Next, the main storage compartment can be slid into the base, then the box removed, which drops the shotgun shells into the main storage compartment.
