125 mm HE, HEAT &APFSDS
Single base seven perforated propellant cylindrical grain, 12/7 VA containing Nitrocellulose (NC) and Diphenylamine (DPA) and tubular propellants: 15/1-240 and 15/1-352 is a kind of single base propellant containing Nitrocellulose (NC) and Diphenylamine (DPA). 12/7 VA propellant is used for 125mm Heat and HE ammunition. This ammunition is used for 125mm gun fitted on T-72 8T-80 tank. 12/7 VA, 15/1-240 and 15/1-352 propellants are used in propelling charge in APFSDS ammunition for 125mm tank gun type T72
