Personally, I would shoot the Barnes TSX or any other Barnes big game bullet.
The partition would be my second choice.
The game king would not be an option.
The partition is designed to retain weight and structural integrity while penetrating through thick skinned, dense bone structured animals.
It does not do much in the form of expanding.
The Barnes on the other hand is designed with the same intentions, however, it expands.
There is not a better bullet on the market, imho, than BARNES.
