Abstract
A two piece aerodynamic pusher consisting of a body and tailpiece. This pusher fits into a standard 40 mm cartridge case by means of three sabots. After the cartridge case is functioned, the combustion gases push the projectile forward and ignite a delay column located in the rear of the pusher. Upon muzzle exit, the sabots discard and the pusher continues down range as the delay column burns. Once the delay has burned, a charge located in the pusher body is ignited, pushing the payload out of the front of the projectile. The cap pops off, and the pellets are dispersed. This effectively moves the payload release point from the muzzle until a designated point down range based on the delay length.
