Description
This cartridge is fired in 60mm mortars M2 and M19 for target practice and contains a spotting charge for observation.
The complete round consists of a projectile body, a point-detonating fuze, a fin assembly with a 2 inch extension, four increments of propellant charge, and an ignition cartridge with a percussion primer. The projectile body is of forged steel or pearlitic malleable iron (PMI), and is threaded internally at the nose to accept the fuze and at the base to accept the fin extension. The body is loaded with an inert plaster filler to simulate the weight and ballistic characteristics of a high explosive cartridge. A pellet of black powder for a spotting charge is loaded in a cavity just below the booster casing of the fuze.
