Cartridge, 105 mm: HE M1

deep cavity projectile for long intrusion fuzes may be loaded with 2.087 kg of Composition B or 1.93 kg of cast TNT, plus a supplementary charge consisting of 136 g of TNT pressed into an aluminium liner found below the nose-located fuze well. Shells have been filled with RDX/WX6 or RDX/WX8. Normal cavity projectiles are packed either with a fuze or a closing plug in place of a fuze. Deep cavity projectiles may be packed with the supplementary charge and a fuze, the supplementary charge and a closing plug, or with a closing plug only. A groundburst detonation of a 105 mm HE M1 projectile will result in a lethal area covering from 288 to 290 m 2. The cartridge case is of the M14 type. Charge 4 consists of Charge 3 plus a 96.39 g increment of propellant M1 (large size). Nominal charge weight is 446.79 g. Charge 5 consists of Charge 4 plus a 153.09 g increment of propellant M1 (large size) and a sheet of lead which functions as a decoppering agent. Nominal charge weight is 599.88 g. Charge 6 consists of Charge 5 plus a 243.81 g increment of propellant M1 (large size). Nominal charge weight is 843.69 g. Charge 7 consists of Charge 6 plus a 369.89 g increment of propellant M1 (large size). Total nominal charge weight is then 1.241 kg.
