My mortgage costs more then my disposable income. Disposable income is what's left over after i pay all my bills, right? so comparing my mortgage bill to disposable income is a fallacy at best...i can choose to allocate more funds toward my mortgage or more towards being 'disposable'... It all depends on lifestyle.

Well correct me if I'm wrong but railguns do damage by firing slugs at extremely high speed and using kinetic energy to inflict damage onto the target

You're wrong. A railgun uses a magnetic field as the *source* of the kinetic energy instead of gunpowder. you could, feasably, have a railgun slug that carries an explosive payload. after a railgun projectile leaves the gun, it behaves just like any other projectile. parabolic trajectory, affected by gravity and aerodynamic drag, etc.
