Most of my hunting here is very similar, the 7mm are a great choice, I have recently acquired the sambar bug which has taking up all of my hunting time this year. I had a 6.5x47L built on a 700sa a couple of years back which I use for long range fallow, goats and pigs. Look up Ballistic Studies there in NZ, Nathan Foster has a lot of good information on hunting, bullet selection etc.
