It should also be noted that we don't know the OPs experience level or skill level. Which was covered when cubslayers said "I'm not saying this is you..."
This deer traveled just over 50 yards through some very thick brush with the top of the heart gone and both lung shredded on the bottom. If that was a high lung "void" hit it would have went further, without much blood probably. The chest cavity would be full when you gutted it, but you might not get much on the ground for tracking. It can be a very difficult shot to track.
But it's still a fatal shot- no doubt.
