Metal Storm Metal Storm is capable of firing a million rounds per minute. That's 16,000 rounds, per second. The Metal Storm system fires so many bullets in such a brief amount of time, into the exact same location, that it's likened to firing a javelin.
A javelin made of bullets. This gives the system superior armor-piercing potential, since if one bullet isn't enough to break through, the other 16,000 probably will.
