Capacitor charging circuit using bd243c. Will it work?? Answered

i recently made a schematic to charge a capacitor bank for my coilgun.D1-D4 are all 1n0007

t1 is a centre tapped transformer which will step up 12v to 330V. WIll it work.
r1 and r2 are 10w resistors.
Q1 and Q2 are BD243C with a rating of 65 watts.
 i found my transformer from a very old cassette player. huge and heavy able to pump about 100W.

i don't bother about charging time. I just want to know if it would be good. don't worry about the voltage monitoring i have a small voltmeter(like a watch. chinese product.)
i am just want to know if it will work or not

UPDATE:
I have tried the shematic. It works flawlessly.

I can see its supposed to be a self-exciting oscillator, try it, it might work, it should work.

The only thing wrong is it may oscillate too fast for your magnetics.

If you're feeding Q1&2 from a flat DC supply, I'm not seeing this working -shouldn't that be 12VAC?
