On January 31, 2008 the US Navy tested a railgun that fired a shell at 10.64 MJ with a muzzle velocity of 2,520 m/s (8,270 ft/s). Its expected performance is a muzzle velocity over 5,800 m/s (19,000 ft/s), accurate enough to hit a 5-metre (16 ft) target over 200 nmi (370 km) away while firing at 10 shots per minute.
The Metal Storm is the World's fastest machine gun. It fires 1660 bullets in every second up to 1 million rounds in one minute. It's a machine gun that has no trigger or any h â¦ ammer, it can be unmanned without having some to crank it up.etal Storm is NOT a machine gun. It is a modern version of what is called a volley gun; a classical example of the volley gun is the French mitrailleuse (a contemporary of the Gatling Gun). All rotary cannons (such as the Gatling Gun or miniguns) are also NOT machine guns.
