Take half the ammo, 1/4 of the clothes and twice the money that you think you need. Ignore the first if you want to give it away. If you do end up taking the airline limit, put half of your ammo in your friend's luggage and take half of his. That way if you lose your luggage you'll still have more than enough.
Travel in footwear you can wear hunting. It doesn't hurt to travel in huntable clothes either. Have at least enough clothes in your carry-on that you could get through if you had to.
Scan every scrap of paper, every document, a note from your mom, your passport, your ticket and anything that could conceivably be needed and email it to yourself. That way if your are standing in Africa with nothing but the clothes on your back and a money belt, you can still go hunting with a borrowed rifle. More importantly you can get home, and if some of your stuff eventually shows up you can get that home too.
Never smile at the local girls. Ever.
