Its well overdue time that one of the Sponsor Companies started arranging things like this. Ship them in crates ahead of time to an agent, and then uplift once you arrive. A Dealer/manufacturer would have more clout/knowledge to get this done, import/export permits arranged, and a dealer/agent at the other end arranged to hand them out and collect them afterwards and ship them home again.
I think with the new rules around excess baggage that came in after 2009 Worlds, it would be more cost efficient to do without your rifle a few weeks and send it over in advance than try to take it with you personally.
I'd like to hear what main sponsor Companies might be able to do in this regard in the future......they have the clout and the experience in shipping the things.
2 cents worth.
