An explosive composition for use in telescopically expanding non-lethal training ammunition comprises tetrazene and paraffin wax. The explosive composition can be used as a primer and/or as a source of energetic material in a telescopically expanding non-lethal training cartridge; it can be used to propel a projectile from a telescopically expanding non-lethal training cartridge; and/or it can be used to expand telescopically a non-lethal training cartridge within a host gun.
A cartridge for use in a gun comprises a case, a gas generator, a piston, a stopper, and at least one channel for the passage of gas in and / or around the stopper wherein the piston is axially slideabiy contained in the case, the gas generator is located within the case adjacent a first end of the case, and the stopper is slideabiy contained within the piston for closing the at least one channel.
The invention provides a marker projectile a hollow body (4) having an opening at the front; a marker substance (3) disposed within the hollow body (4); and an expelling member (5) within the hollow body (4) behind the marking substance (3); the hollow body (4) and expelling member (5) being configured such that upon impact of the projectile with a target, the momentum of the expelling member (5) relative to the hollow body (4) carries the expelling member (5) forwardly to expel the marking substance (3) through the opening, a separator (1) extending at least partly over the front opening, the separator (1) defining two or more spaces through which the marker substance (3) may pass when expelled through the opening and characterised by a deformable closing member (2) positioned between the marking substance (3) and the separator (1), the closing member (2) configured to deform under the impact of the travelling expelling member (5) whereby to release the marking substance (3) from the hollow body (4).
