I shoot a little bit, and though I would have no problem playing on a range out to 500 meters with a .308, I am never going to take a shot at game with one at that distance.
The .308 is a great caliber. However, in .30's I much prefer a 180 gr bullet - particularly in Africa. The .308 is not ideal for such a bullet weight. The 30-06 is much better, and the .300 Win Mag is superb with that bullet weight. The target area in African antelope is just a tad farther forward and lower than North American or European deer. Forget that and you are often hitting a little too far back, where an exit wound can really aid your tracker. Even more likely, assuming you hit your target correctly, you are driving a bullet through muscle and bone. A premium 180 at sufficient MV buys you a critical bit of insurance. Remember, a drop of blood equals a trophy fee.
And no, a typical heavy for caliber 7mm will drive much deeper than a typical 150 fired from a .308. But then again, based upon my experience shooting African game, I am all about penetration.
If you don't want to buy another rifle - fine. Don't. You can have a very successful plains game safari with your .308 - many people have. Just don't expect a majority of hunters with meaningful plains game experience, to agree it is an ideal choice.
