Namibia Hunter
AH member
30-06 and .308 Win with standard 180gr cup and core bullets have probably killed more plainsgame in Namibia than any other caliber and bullet weight combo. Very few locals here hunt with TSX (to my knowledge) and I do not have any personal experience with them in 30-06. However, all of the animals on your list will and regularly do go down with a 180gr lead based pill to the heart lung area. At 200+ meters cup and core bullets will hold together just fine and penetrate accordingly. If you are not convinced and want to go "premium" then Partitions will also perform excellently. Don't overthink it and enjoy your hunt!
