The NORINCO 130 mm ERFB/HB HE and ERFB/BB HE is the NORINCO 130 mm ERFB HE projectiles are separate loading munitions with their propelling charges contained in brass cartridge cases. The bodies of all these 130 mm ERFB HE projectiles are high-grade steel and are streamlined to the extent that almost the entire length is taken up by the ogive down to the twin copper drive bands. There are four riding nubs provided. The ERFB/HB HE uses a boat tail hollow base while the ERFB/BB HE is fitted with a Base Bleed (BB)
unit to provide increased range; maximum range is 37,000 to 38,000 m. The explosive filling for these projectiles is usually 3.3 kg of TNT. Weight of the ERFB/HB HE projectile is 32.7 kg while the ERFB/BB HE weighs 32 kg. The ERFB HE (Nubb) weighs 32.41 kg. The weight for the ERFB-B has not been released. The nose-located fuze employed on the 130 mm ERFB/HB HE is the ML-5, ML-7A or ML-7B while that on the ERFB/BB HE is the ML-5 which can be set to super-quick, short or long delay. The ERFB/BB HE may also be fitted with an electronic fuze of unspecified type. These ERFB projectiles do not employ a special charge system but instead are used with the usual 130 mm variable charge system. The 70:30 drawn brass cartridge case involved is issued in two versions, a Full Charge version and a Reduced Charge propellant load. The Full Charge contains 13.5 kg of propellant loaded in a lower and upper bag, together with 2.5 kg of loose propellant in bundled stick form. An increment completes the Full Charge while removal of this increment creates Charge 1. The Reduced Charge weighs 6.75 kg and is supplied in a separate cartridge case. The top charge in the Reduced category is formed using the full complement of a base charge and two equal sized bags, forming Charge 2. Removal of one of the equal bags creates Charge 3 while removal of both equal bags, leaving only the base charge, creates Charge 4. A percussion primer is pressed into the cartridge case base to ignite both Full and Reduced propellant loads.
