I have absolutely zero African experience, but just as a word of encouragement, Jack O'Connor once observed 180 grain bullets from a 30-06 completely penetrating the shoulders of a grizzly bear and hitting the sand bar behind the bear. Allen Day, who has tons of experience says the 180s will do fine from your 300wm ... I say check everything out, try your favorite load, and go live the dream. Oh, and post pics to the campfire when you're done!!
All the best,
Liam
