Rapid Fire Coil Gun

Have a look at this cool rapid fire coil gun, it was created by the same guy that made this one.

“The Injector is a high power solenoid designed to push the projectiles out from the magazine into the coil breach. The armature/piston is made out of the same steel as the projectiles but of a slightly smaller diameter. The length is twice as long as the coil so that when the armature is magnetically sucked in to its max insertion point, there is > 1/4 length of armature protruding out of the injector coil. This 1/4 length of steel is what produces the work on the projectile.

The combination of armature, coil, spring, and housing mixed with pulsed voltage produces a hard hitting injector. The injection force must be strong to counter act the tension extered on the projectile from the magazine spring. The initial projectile speed must be fast to prevent jamming in the accelerator breach.
