coil gun help!

i am building a coil gun and i need help. what is a good material to use for the barrel? a Pen tube? i did a test using on cap and it went about six inches with barely any wire for its coils. how fat do you think i can get a small nail going with 4 caps at 300v at 450 uf? also, does the projectile have to fit snuggly in the barrel. i am using magnetic wire from a motor taken apart. so, how many windings should i have?

i hate say it, but the diode will probably not protect the circuit and will steal power from the coil gun. thats why i said safety gap.

To Tech-king: I promise I will not make any HV projects. What's RCRL? Resistor Capacitor Resistor Inductor? I'm making a wireless power inductive power transfer device thingamagij, that doesn't count, right? Tank Circuits, yummy.
resonant capacitance, resonant inductance. basically a tesla coil or other resonant transformers or frequency generators.
ohhh, you mean to resonatley (the adverb of resonant) step up voltage to insane levels. I'm just using resonant coils to transfer power without wires efficiently.

i dunno, well I have an idea, but ask tech-king I know he's not as quick to respond as me ;) but do you really wanna risk saftey?
im not that slow! i was asleep. it was 10 oclock easter time.

you dont. the coil goes to rf ground, the caps to charger circuit ground

you have to charge it to full power, and you need to discharge it through the coil

lol
well I don't wanna give you any more info cause I don't want you to die ;)
