Congratulations on the booking of your safari!!
I took the same rifle/scope combo to KZN last September and found it to be very adequate. My shots in the bushveld were from 80-200 yards and often involved some brush in between. In my 1983 M70 I had good luck with nosler 260 gr. soft points. After using 300 sp for plinking and practice, the 260's felt quite a bit lighter as far as felt recoil.
I second the recommendation of considering Nyala as a target species. When planning my first ever safari, I originally had not considered Nyala because of cost, but was convinced by a friend who had been to the Natal several times. It ended up being the keynote of my hunt. KZN seems to consistently produce some of the best quality in RSA. Nyala was the animal we saw the most of every day by far. So many different bulls and different horn shapes. I had many opportunities to pass on good, and even great bulls and look for incredible.
If you have any thoughts of taking a grey duiker, which are also everywhere, buy a box of solids to bring along. Your taxidermist will thank you. Though my 260 sp didn't blow it to pieces, there wasn't much choice on which way the full mount would be facing.
If you want to whet your appetite I posted a very long hunting report with many pictures. "14 days in Qwa-Zulu Natal, a beginners journey" My wife and talk about wanting to go back nearly every week since then!
Have fun planning and safe travels!
