ABSTRACT:
A battery pocket for centerfire sporting ammunition, for example a shotgun cartridge, comprises a cap shell containing a quantity of impact-sensitive priming material, an anvil and a cap chamber having one or more flash holes therein, the or each flash hole being closed by a layer of material that is removable upon, and as a result of, impact-ignition of the priming material. The or each layer preferably comprises a particulate material, such as china clay, in a polymeric binder and the provision thereof renders the battery pockets less mass-explosible.
