On light game, Partitions will punch right through. If you don't hit any heavy bones, they really punch right through. If you place the shot correctly, it's still fatal; but generally won't be a "DRT" finale.
Ballistic Tips, on the other hand, are wicked, nasty, explosive little buggers. A poorly placed shot will result in massive wounds, terrible meat loss, and may let the animal escape to die painfully. A properly placed shot, however, often results in the coveted "DRT".
But... I have come to really appreciate the Remington Core-Lokt for light game. It expands nicely, but can still provide deep penetration. Premium bullets can easily be argued to be a waste of money for light game (White tail, Black tail, antelope, etc).
