Multipurpose Incendiary Shotgun Shell
The multipurpose incendiary shell is designed to function as both a tracer and incendiary device. A light metal body is loaded with incendiary compound which is ignited by the propellant charge on firing. Helical vanes on the exterior of the shell impart a spin in smooth-bore shotguns to stabilize the shell.
The phosphor-magnesium incendiary compound is visible during the first 250m of the projecile's flight. Upon striking a target, a second charge detonates and also ignites any remaining compound, showering the target with burning material to a radius of 5 meters.
While the expelled incendiary is of only modest danger to personnel, any flammable material in the area will be ignited.
