This can be influenced by several factors, including operator training level, mechanical limitations, ammunition availability, and weapon condition. In modern weaponry, it is usually measured in rounds per minute (RPM or round/min) or rounds per second (RPS or round/s). [1]
The GAU-19/A is designed to accept standard NATO .50 caliber M9-linked ammunition. The rate of fire is selectable to be either 1,000 or 2,000 rounds per minute. The Humvee armament kit version fires at 1,300 rounds per minute. The average recoil force when firing is 382 lb/ft, 495 lb/ft or 629 lb/ft depending on firing rate.
A MANTIS system consists of six 35 mm automatic guns (capable of firing 1,000 rounds per minute), a ground control unit and two sensor units. The guns fire programmable AHEAD ammunition, developed by Rheinmetall Weapons and Munitions - Switzerland (formerly Oerlikon Contraves Pyrotec).

The maximum rate depends on the pressure drop rates in the barrel after firing a cartridge, on mechanical tolerances, and other factors. For example, the 7.62mm NATO version EX-34 was advertised to fire 570 rounds per minute, and developmental work was underway for a 1,000-rounds-per-minute version. In practice, chain guns usually have two or ...
The modifications to the basic MG 42 design include an extra heavy bolt (950 g (33.51 oz) vs. the 675 g (23.81 oz) MG 3 bolt) which reduces the cyclic rate of fire to around 850 rounds per minute. The rate of fire can be varied up to cyclic rate of fire of around 1,150 rounds per minute, if necessary, by changing the bolt and return spring.
For example, 1000 rounds per minute of continuous fire from a conventional single-barreled weapon ordinarily results in rapid barrel heating followed by stoppages caused by overheating. In contrast, a five-barreled rotary gun firing 1000 rounds per minute fires only 200 rounds per barrel per minute, an acceptable rate of fire for continuous use.
1,000 rounds per minute The Bailey Machine Gun was a rapid-fire weapon developed in the late 19th century. It was a multiple barrel weapon similar to the much more commonly known Gatling gun , and was the first weapon of this type to be belt-fed.
