There is no question that you didnt get a lung shot. If you had gotten a lung shot there would have been blood somewhere. bears can live on one lung...it is VITAL to double lung them. Also, contrasry to popular belief. It is actually better to shoot a little higher on a bear than what a lot of people think. Not at the level of the shouklder but...there is so much fur on a bear ecspecially on the belly/ underside that it appears that this is body when in reality it is fur and NOT a kill zone. This is a major consideration for trophy bear hunters in the spring where there is still the heavy pellage of winter on them.
