| Description: |
|---|
| The projectile consists of a hollow steel forging with a boat-tailed base and streamlined ogive. The projectile nose is threaded to receive an adapter for the point-detonating fuze and to provide a seat for the burster casing assembly. The burster casing assembly a thin-walled steel tube containing the burster charge and burster initiator, extends from the adapter to the rear of the projectile cavity. The burster tube provides a tight seal for the charge of white phosphorous (WP). The M313C is identical to the M313 except for a different propellant charge which gives a lower muzzle velocity and a resultant reduction in gun wear. |
| Use: |
|---|
| This cartridge is used in 90mm guns for spotting and screening purposes and has a limited incendiary effect. |
| Functioning: |
|---|
| When the weapon is fired, the burning propellant creates gases which propel the projectile out of the gun tube. Upon impact, the pointdetonating fuze functions igniting the burster initiator and detonating the burster charge. The projectile casing ruptures, dispersing the filler. WP ignites upon contact with the air, producing a dense white smoke and flaming particles. |
