Bramble has given you some good advice there. As you live in Oz, use the Woodleigh SPs for your plains game and if you want, you could step up to the PSP for the eland and a Buff if you take one.......although with that calibre, the SPs would probably do. If you do use Woodleighs, pay very careful attention to the speed limitations printed on the box.

Depending on area you hunt, your shots might be longer but assuming you hunt the bushveld of RSA/Zim etc, the range estimations Bramble gave you are about right.
