You are assuming you will pass through. If you hit the shoulder bone just right it will not. Quartering away shot the vitals have been taken out before it reaches the opposite shoulder. Lung hit deer with one of his running gears taken out equals short tracking job. Deer with broadhead stuck in shoulder bone equals a deer with a real bad limp until someone finishes him off. Before you answer back with KE let me tell you this I shoot a 413 grain arrow at 279 fps and have failed to bust the shoulder bone. Luckily the neighbor finished him during rifle season.
