I'd have to say that it would be very hard for a deer to survive a lung shot! With just one lung being hit, it may survive a little longer, but eventually, it is going to drown in its own blood!
As far as the buck picture, with all the photo editing programs these days, I'd have to see that deer or know the person that took the picture!
If its real, it does look like a steep angle, too far back!
The one thing that makes me think "phoney," is I don't think a buck with that kind of wound would be standing at a bait pile!
