Hate you didn't find your critter, but 2#$% happens. No need to get defensive but several have given you support and constructive criticism and they are not attacking. Reguardless of bullet choice several have reported dead critters with the shoulder shots. Like someone else said there are three shoulder shots and all have different results. Must have been some quartering, cause I know that bullet will bust both shoulders and keep on getting it. And any critter with no front running gear ain't going far. Good luck on the rest of this years hunting ventures.
