ok, here is my coilgun setup, there is the gun, the target the mount, the ammo.
the mount is just an old drill press vice, works good, the ammo is a piece of 3\8-16 grade 5 bolt that i cut off with a hacksaw.
there is a clip attatched that shows the test firing at 280Vdc ill do it again with 358Vdc or even the peak voltage of the caps.
and here is the poor can that was shot with the 3\8 bolt, Exit wound.
