The only province (out of 9) in South Africa that does not allow 9.3mm, is Natal. Even some of the nature conservation authorities have it wrongly that .375 is minimum in the old Transvaal. (Minimum .358, but never very widely known in old Transvaal) Freestate does not have a minimum, can legally hunt with a .22 rimfire. However, most outfitters in SA will advise clients to hunt with .375 and bigger, maybe out of ignorance, or maybe for safety sake. I personally believe that the 9.3's (x64, x62, x74) are all very good calibers for hunting buffalo and lion, if very good bullets are used. (I am referring to sport hunting, backed up by PH with larger rifle handy in case of sticky situation.) Marinal for elephant, rhino, and hippo (on land), but so is a .375Whatever.
