💥 M203 Propelling Charge, 155 mm (Red Bag, Zone 8S)
Product Introduction
The M203 is a high-zone propelling charge designed for 155 mm artillery systems, providing maximum range for long-distance fire missions. The charge uses M30A1 triple-base propellant packed inside a scarlet-dyed acrylic/viscose rayon jacket, with a black powder base igniter pad and molded nitrocellulose tube igniter for reliable ignition. A lead foil decoppering agent and TiO2/wax wear-reducing additive extend gun-tube service life. The donut flash reducer minimises muzzle flash signature during firing.
