ARTILLERY After the cooking off of artillery shells in the G-5 Field Gun in the late 1980's, the South African army changed commands from "cease fire" to "cease loading". This allowed crews to fire any loaded shells to prevent them from heating up and exploding. CASELESS AMMUNITION Caseless Ammunition eliminates the Metal case that typically holds the Primer or igniter and the explosive charge ("gunpowder") that propels the bullet. The metal case absorbs a large portion of the waste heat of firing. Ejecting this hot, empty case removes that heat from the weapon. With caseless rounds, other means of reducing waste heat are necessary, especially in automatic fire. GRENADES Cooking off also refers to the practice of waiting a few seconds before throwing a Grenade after starting the timer (typically done by pulling the pin and releasing the handle). This enables the thrower to achieve a lethal Air Burst over a target or provides the least opportunity for the target to throw the grenade away or back at the thrower. RIFLES Cooking off is a characteristic of certain Machine Gun s, especially those firing from a closed bolt, that are air-cooled, and capable of sustained use. When the trigger is released, the weapon feed leaves a final round in the chamber, where heat ignites the propellant firing the round. Cooking off limits the Rate Of Fire of many Rifle s, since heavy use will heat up the gun's barrel. In the case of the US M296 or other Squad Assault Weapon s sustained fire of only a hundred rounds per minute can create sufficient heat. Inefficient or insufficient cooling of the barrel or chamber causes either a cook off or stoppage of the gun through metal expansion. Wait 10-15 minutes before attempting to clear a jammed gun with a hot barrel. TANKS Cooking off is a serious hazard to crews in damaged and disabled Tank s. Attempted solutions include storing ammunition under water and insulating ammunition compartments. The current technique, used in tanks like the M1 Abrams , is to armor the compartments and provide blow-off panels to channel the force of the explosion to the exterior of the tank. |
