155 mm (Green & White Bag Charges)
Single base one and seven perforated propellant cylindrical grains contain Nitrocellulose (NC), Diphenylamine (DPA), Dinitrotoluene (DNT), Dibutyl Phthalate (DBP) and Potassium Sulfate. One perforated propellant is used in zone 1-5 (green bag charge) and seven perforated propellant is used in zone 3-7 (white bag charge). These charges are used in 155mm gun
