What does the term 'cook off' refer to?

The term 'cook off' refers specifically to the premature functioning of the propelling charge due to heat. This phenomenon occurs when the temperature of the ammunition rises to the point where the combustible components ignite without the normal firing mechanism being engaged. This can happen in situations where ammunition is exposed to high temperatures, such as when a weapon is fired in rapid succession or when it is left in a hot environment. The significance of understanding 'cook off' lies in the potential hazards it presents, as it can lead to unintended discharges of the weapon, thereby endangering personnel and equipment. Proper ammunition handling and storage practices are essential to mitigate the risks associated with this occurrence.
