Would 3 camera flash caps make a strong enough bank for a coil gun? Answered

I've got 2 capacitor banks right now. The first one uses 3 300V, 120uF capacitors, and the second uses 2 16V, 1000uF caps. Is either of these strong enough to make a coil gun that fires 2mm iron pellets at around 200fps? What if I give it a second stage? Also, I've already made 2 coils around plastic tubing, one using 3 layers of 16 gauge wire with 15 turns each, and the other with 5 layers of 20 gauge with 25 turns. Which one would give me the most power?
