I have also heard people say they shot a deer right in the heart, but the lousy cartridge they used (and never will again) wasn't enough.
But I am not talking about "guessing" that bullets came apart and failed to penetrate an animal. As noted, I have seen a number instances where that was PROVED to be what happened. Again, just because YOU haven't seen it doesn't mean it can't happen.
