Bob just go to Customs and get a 4457 with both rifles on it in your name. Put both in one gun case (been there, done that) When you get to Joburg they will want to see your 4457 with the s/ns on it and the SA police papers filled out with only your name on the rifles. Its as easy as that. You won't have any problems. Make sure you weigh the gun case before you go to the airport. Don't lose your papers as you'll need them when you leave for home or if you are checked at a road block somewhere. If you want more ifno let me know.
