it has already been mentioned in this thread but id like to add that the extra small meplat (the very tip of the bullet) and also that the jacket of the bullet thins in this area of hollowpoint match bullets is what makes them a big no no for hunting. if the bullet is placed on soft tissue the bullet will expand properly and the deer will actually go down nicely. if the bullet is placed on hard bone there is a chance to colapse the nose of the bullet which will basically turn it into a fmj and only pencil hole through the deer. proper hollowpoint hunting bullets use larger meplats or in the case of some of the new vld style bullets (berger, wildcat, lutz moller, gc custom) they use harder jacket material or the nose area is otherwise reinforced.
obviously there are uses for bullets that expand rapidly or not expand at all, but who wants to shoot a bullet that will do both depending on shot placement? the key to any hunting bullet is repeatable results. if its a varmit bullet it should blow up inside a animal, if its a fmj it should pass through a animal if your finishing off a wounded deer.
