Inside of a worst-circumstance circumstance this will likely lead to a cartridge to overheat and detonate even if the set off isn't pulled, potentially bringing about destruction or resulting in the gun to cycle its motion and preserve firing until finally it has exhausted its ammunition source or jammed (this is referred to as cooking off, unique from runaway hearth exactly where the sear fails to disengage when the result in is produced). To forestall this, some sort of cooling program is required. Early machine guns were being generally drinking water-cooled; although extremely effective, the h2o also extra significant excess weight to an already cumbersome style and design.

With hoppers, the rounds could generally be added although the weapon was firing. This little by little changed to belt-fed varieties. Belts ended up possibly held within the open up by the individual, or in a bag or box. Some modern day car or truck machine guns used linkless feed methods even so.
