Coilgun stages?

I want to make a coilgun, but i didn't know if I should use 1 or 2 stages. I want to use capacitors  rated 450v, 1000uf, I have ten of this capacitors.

If you want to use multiple stages.

450 volts

A coil gun is about imparting linear acceleration energy to a projectile to
attain very high speed.
What voltage are these capacitors ?
Energy stored in a capacitor is C* V*V/2 ... You can see energy stored in a
capacitor increases as the square of the voltage.
