This is the most powerful mobile electromagnetic railgun built by a non-government. A railgun is a device that accelerates a conductive projectile using extremely high current and electromagnetism. No explosive powder required. Just batteries. This page shows many of the steps required to make one.
The gun is portable, but the power supply is not. Still, cool project.

That's because they used aluminum projectiles. The heat blew the material apart as if it had been hit with a plasma torch. Use ferrous projectiles and see what happens.
When life isn't going right, go left.
