The 120mm Tank Gun in Chieftain and Challenger I are identical, the L11. The Challeger II uses the L30 gun. Both ammunition sysytems are separate loading, ie. Projectile and Charge are loaded individually. To call it a"bagged charge" is a bit simplistic, the Charges for both systems are held in a Consumable Cartridge Case (CCC), a rigid tube made from nitro-cellulose and paper. It is laquered to give it envoronmental protection and physical strength. As the CCCs contribute energy to the charge system, making them is a "Black Art", perfected by the ROF at Bishopton, Glasgow. Ignition is effected by using an electric cartridge, not unlike a blank. Jim Franklin Orpington KENT.
