| Description: |
|---|
| The projectile of this cartridge consists of hollow steel forging and is similar to the projectile in the M1 cartridge. The projectile is loaded with approximately 4.6 lb (2.1 kg) of Type 1 TNT only. "Composition B" cannot be loaded with cartridge M760 as it is too sensitive for use with propelling charge M200. The propelling charge M200 is a single bag charge consisting of 4.25 lb (1.93 kg) of M30 propellant, The bag charge has a hole through the center for fitting around the primer in the cartridge case. The M200 propelling charge is for extended range firing (Charge 8) for 105mm, Howitzer M119 use only. The cartridge case used is the M14B4 (3- piece spiral-wrapped steel). The mouth of the case can expand slightly by uncoiling, This makes it easier to insert the projectile in the mouth of the case, However, if the loader is not careful to grasp the projectile at its center of balance, the lip of the mouth of the cartridge may protrude enough to catch on the lip of the lower extractor recess, making it impossible to chamber the round, The cartridge case may be manually rotated and seated with no adverse effect on the ammunition, The primer used is the M28B2 percussion primer (300 grains of black powder). |
| Use: |
|---|
| This cartridge is a high explosive round initially developed for use with the Howitzer, Light Towed, 105mm: Soft Recoil, M204, Currently, the M760 Cartridge is only authorized for use with the Howitzer, Light, Towed, 105mm: M119. |
| Functioning: |
|---|
| The weapon firing pin strikes the percussion primer of the cartridge case igniting the black powder of the primer tube which ignites the propelling charge. The pressure build-up from propellant burning propels the projectile. As the projectile is propelled through the weapon tube, the rotating band engages with the rifling, imparting spin to stabilize the projectile. Projectile functioning is dependent upon the fuze used and may function on impact (instantaneous or delay) function above ground either at a predetermined height based upon time of flight or function in proximity with the target area. Fuze function detonates the supplementary charge, and the supplementary charge detonates the high explosive projectile filler resulting in projectile fragmentation and blast. |
