The thing abut coilguns is once they get powerful enough to start killing things you'll still probably not be able to hear them fire, and if you do it wont be very loud or sound like a gun. They have an advantage over railguns in that the coil doesn't erode with every shot. Also railgun shots are obvious, they have a big trail of sparks and plasma coming off the end of the shot.
A railgun passes voltage through the shot, and the discharge blasts pits out of the rails each time. Kind of like how a capacitor can blow a small pit out of a steel screwdriver, or your arm if your not careful.
I made a coilgun powerful enough to punch through cardstock with some disposable cameras, a straw, and $5 worth of magnet wire.
