On a more serious note, if Pigs are such a problem, I cant imagine why folks down there do not offer "Guided Hunts" Its big money in the States. I would love to come down and get a couple. Just bought a brand new .17wmr Ruger with Scope and would love to see how it works at a couple hundred yards.
Nothing better than a Pig on the Barbie......(Im sure someone will cap on that last line)
