Hey Baz. My only issue is that you wouldn't normally shoot a pig that size. If there was pigs locally, i would be shoot as many as humanly possible. They all need to be culled and there's no room for 'leave some for next year'. There's no way you will ever shoot them out, so kill as many as you can for the sake of the local ecology.
Just my take.
Same goes for cats, foxes, feral dogs, goats, camels and brumbies/donkeys.
