I’d hate to guess how many lion and cape buffalo have been killed with a 338 Win Mag. The 9.3 isn’t exactly a legal caliber in most African countries either with .375” being the stated minimum. Show me where a 9.3x62 hurls a 300 gr load faster than a 338 Win Mag.
The 9.3 has been the go to gun for so long in Africa, I don’t think that are many African countries that are stupid enough not to grandfather it in to its “legal” big game list.
