For sure use an expediter. It will save you hours at the SA police station at the airport. My last trip in April '08 took less than 5 minutes to get through the gun business. Google Air 2000. Cost about $175 - money well spent. BTW, I packed my ammo in my rifle case. Went from Reno to Jo'burg to Maun, Botswana with zero problems. Remember to keep your permit paperwork with you at all times. I saw a bunch of Spanish hunters in Maun going through customs with their ammo in steel boxes with nothing written on the box. Dunno ... would use boxes properly marked.

Saw some gynormous buffalo. I only got a little one - 40 inches with a .458 Lott. He did the two-step and was down and out.
