Rate of fire may also be affected by ergonomic factors. For rifles, ease-of-use features such as the design of the bolt or magazine release can affect the rate of fire. For artillery pieces, a gun on a towed mount can usually achieve a higher rate of fire than the same weapon mounted within the cramped confines of a tank or self-propelled gun ...
This configuration eliminated the need for a single reciprocating bolt design and allowed higher rates of fire to be achieved without the barrels overheating quickly. One of the best-known early rapid-fire firearms, the Gatling gun saw occasional use by the U.S. forces during the American Civil War, which was the first time it was employed in ...
The history of the firearm begins in 10th-century China, when tubes containing gunpowder projectiles were mounted on spears to make portable fire lances. [1] Over the following centuries, the design evolved into various types, including portable firearms such as flintlocks and blunderbusses , and fixed cannons, and by the 15th century the ...
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.
The M2 has varying cyclic rates of fire, depending on the model. The M2HB air-cooled ground gun has a cyclical rate of 450–575 rounds per minute. [29] The early M2 water-cooled AA guns had a cyclical rate of around 450–600 rpm. [30] The AN/M2 aircraft gun has a cyclic rate of 750–850 rpm; this increases to 1,200 rpm for AN/M3 aircraft guns.
The Vulcan's rate of fire is typically 6,000 rounds per minute, although some versions (such as that of the AMX and the F-106 Delta Dart) are limited to a lower rate, and others (A-7 Corsair, F-15 Eagle) have a selectable rate of fire of either 4,000 or 6,000 rounds per minute. The M61A2's lighter barrels allow a somewhat higher rate of fire ...
As the first war experiences in the beginning of World War II proved that a higher cyclic fire rate generates more dispersion of the bullets, MG 34 based prototype guns like the MG 34S were requested. The MG 34S had a shortened and lightened barrel, a stiffer multi strands recoil spring and a better recoil booster to increase the rate of fire.
The gun fired the "Long Solothurn", a 20 × 138 mm belted cartridge that had been developed for the ST-5 and was one of the more powerful 20 mm rounds. [2] The C/30, featuring a barrel length of 65 calibres, had a fire rate of about 120 rounds per minute. It proved to have feeding problems and would often jam, which was offset to some degree by ...
