Coil switching

[bte]

I've breadboards a driving circuit using irf710 MOSFETs. I'm getting retriggers when pulsing my tetra. Would anyone be willing to help me design and troubleshoot a proper driver? I'm on my phone due to no Internet but I can post a schematic of what I have so far. Before make a PCB I just want to make sure it will work on not ring all over the place and false trigger. It starts acting up at around 100 volts but is reasonably stable below that. Nothing is isolated either at this stage.

If someone can help id appreciate it and can compensate time needed if you wish.
