If you bring it to Canberra, I can bring mine and we could swap some parts around to isolate the problem. I have a spare sensor actually. We could do it at the SSAA range. Are you there for the leadup?
Good. I hope get to get there early this year, possibly Monday, so look me up when you arrive. I'll be the one with froth coming out of the mouth - haven't shot a Queens for 12 months so am champing at the bit.
