I live in Australia. I used to rough and wood pigeon shoot mainly as a lad in Bedfordshire, UK. Over the last 20 odd years I have stalked for the majority of deer species in Australia. I have hunted all pest species such as foxes, rabbits, boar, wild goats, buffalo all over the country and NZ.
I presently use a .17HMR for the smaller pests and .308 or 270 WBY for larger pests: but seldom go out anymore.
