If accuracy and price and availability are off the table, I'd choose Barnes TSX every time. They always work well, especially for game "bigger than deer" like elk. They don't spray lead fragments into the meat. They break bones and continue penetrating more reliably than any other bullet in my experience. They and the other mono metal bullets are more likely than most lead core bullets to also give an exit wound, a feature which I also like. I have shot a lot of game with partitions, and still use them and like them, but they are old technology that has been surpassed.
