For supersonic hunting, I think the new Barnes 110 Tipped TSX bullet is worth a look. Should be able to get it to fly in the mid 2000s, with the tip and the nose cavity, we should get good expansion.
So far Midway is the only ones I found carrying them, they are so new, there is no info on the Barnes website, but they are listed in their shop.
Like all Barnes bullets, they are not cheap, $33/50.
