Where did you have the problem, on departure or arrival in Spain?
So far I don't have any documentation for my gun at all for the trip to NZ.
I have phoned Air New Zealand though to register that I'll be bringing a 'Pellet Gun' with me.
Springers don't need a license in NZ or at home, so I'm hoping I'll be ok.
What do Olympic 10m target shooters do? Surely they'll come up against the same problems we do?
