Vapodog,
Congrats on the safari, where are you headed and what are you after?
If you are targeting any of the Big 5, then remember you may need to at least borrow the PH' s .375 for that animal.
Try your question at
www.accuratereloading.com under African Hunting. Be sure to mention your connections: Lincoln to St. Louis, St. Louis to Atlanta, Atlanta to Cape Town. They know the good the bad and the ugly of the different airports and where you can bribe (whoops I mean " tip" ) to make sure they go thru correctly and where you can' t, and where you should " lay over a day and personally check them in (again)" to make sure your rifles stay with you and where you can just catch the next flight and keep going!
