I think this is more of the case with those examples like the 195s that are pointed. With a significant amount of copper in the tips they do tend to penetrate more than those with more open tips. I personally haven't had issues with bergers not functioning but have with SMKs.
Gravity and a large exit= blood trail. Don't need a heart or lungs for it to fall out of the animal. Once the ribs are popped it allows for a pressure gradient to occur, kinda like a gas can with a breather that allows the spout to flow smoother. Sucking chest wounds and/or any hole in the ribs...
