Hunting in S. Africa next week

[65coupe]

Please ..please ..please can someone with recent experience help me out. I'm headed for Johannesberg next Saturday... hunting in the Limpopo Province in the Northern part of the country..Plainsgame. What can I expect at the airport when I arrive in Johannesburg regarding my rifles and 12ga???? How much "hassle" can I expect from SAPS? Other than the SAPS 520 Form and an invitation from my Outfitter do I need anything else. Motivation Letter? ..Import Letter from the local sherif??
Thanks in advance!!!!!!!!!
