metal storm was an experimental weapons program using caseless munitions and an electric ignition system instead of a traditional firing pin+ primer system to fire a round.

They used bullets stacked inside the barrel to conserve space.

the pistol variant had three barrels; two with standard bullets, and one with several small grenades and/or flares.

they were quite badass, but not particularly cost effective, and i think the company went under.
