When you say "both deer were shot in the lungs" did you mean you verified after field dressing that both lungs were pierced on both deer or did you mean the arrow hit the body in the lung area? If both were double lunged, those are two of the baddest assed deer in the world to go over 350 yards.
You are correct, no broadhead is magic and I don't think anyone here claimed that. I agree and as I said broadhead opinions are subjective and folks should use what is best for their set up and what they are confident in.
