How to connect an scr to a coilgun?

I make the rwilsford07 boost converter and it charges my capacitor fine, but when I turn on the scr the 6v voltage regulator stop working(7806). What can be happening?

What kind of SCR? Puck? Brick?

What's the IFSM?
You haven't disconnected the supply from the cap before firing have you ???
