9,3x62 have been one of most used gun in Africa hunting history and it's OK for Buffalo and Leopard...but the Elephant minimum in most of African countries start from 375 H&H...even this might be not enough. Therefore if you are looking for Elephant you should find something bigger...I don't think you will be please if PH should help you to get your first Elephant. But for more details ask from your PH. Also here on site are some guy's from RSA who can advice you about that issue. Never hunt Elephant (to expensive for me) but having the pleasure to be in RSA several time for hunting and have spoken with my PH Mike Birch about that (
http://www.huntthesun.com). By his word's technically my gun 9,3x64 brenneke is enough for any big animal in Africa, also for Elephant and he can accept it but law is law...for Elephant 375 H&H is required minimum...
