Scenario – I am a heavy and the other player is a heavy. I come around a corner behind him and start to unload into his back and the back of his head. About the first shot, he pops his shield and I continue to unload as he turns to fire (More the 30 feet away so he does not have a shotgun). I pop my shield and continue to fire (am not missing him). He turns POP I am dead and he still has part of his shield left. What am I missing here?
