Coilgun Capacitor Question?

I have a big capacitor that I found in my old xbox. It's 250 volts and 470uF. Would this be better than using a bank of 8 camera capacitors?

heres a calculator
not that the math is that hard

defiantly the photo capacitors they amount to 35-50 joules rather then the xbox capacitors 15

if you find another capacitor thats 470uf and atleast 165v you can combine it with that one in series and you will get 235uf at twice the voltage rating of the capacitor with the lowest voltage rating
