SAKO,
My experience on a LOT more than 5 animals is the same as Formidilosus's.
You can indeed compensate for the smaller wound channel of hard bullets to a certain extent, but softer bullets will still kill more quickly on average. And I have seen deer punched through the "shoulders" (a pretty broad definition) with a TSX got a lot further than 20 yards.
One example: My wife and I spent considerable time one evening looking for a mule deer buck she'd shot through both shoulders with a 100-grain TSX from .257 Roberts. The muzzle velocity was 3150 fps and the range only 50 yards, so it didn't lack for zip. Yet the deer stagged off through sage taller than itself for around 75 yards before going down. There wasn't a blood trail, contrary to what we often hear about TSX's, and it took 45 minutes of spiraling the area where the deer had been shot to find it.
