Here is my first coilgun project(Thanks to anothercoilgunsite and Barry's coilgun site):
Parts list:
C4 5000 uF 800V (Not Sure)
C1-C3 200+ uF 800V
COIL 12 AWG Magnet Wire (6 layers 15 turns per layer = 90 turns) 0.044 mH Inductance ; 0.027 Ohms
D1-D7 1N5408 or other 1000V 3+ A
F 1A 250V Fuse
SW2 Push Button Switch
SW1 250V 2A Switch
SCR 1000V 1000+ A Peak (can be checked in the datasheet of your SCR) ; or smaller voltage and current SCRs in bank (not suro for the first)

And here is the schematic diagram:
Coilgun1

I would be proud to here suggestions and hints about this design.Thanks.

you will need current limiting for scr trigger and charging.
also a 5000uf 800v cap bank seems a lil bit large for a first coil gun.
