I shot 100-120 pound dink last year at 40 yards with a 700. first round hit just behind the shoulder and exited between 4-5 ribs. He actually ran about 15 yards and stopped and started feeding again. second round hit about 2" from the first exit wound and exited the center of his chest. he ran 25 yards and piled up.
That was the last barnes I shot and the last deer I will probably ever shoot with either a 243 or a Barnes.
So you shot a deer through BOTH lungs, through and through, and it just loped on over 40 yards and went back to feeding like it had been stung by a bee? Really now?
Most hunters I know have seen things like this happen in the field. Get out and start hunting and you'll see it sooner than later.

In 35 years of woods time I've never seen an animal, any animal, react that way to a lung shot. I've seem them slowly move away, stumble then fall over. But I've never seen or heard of one going back to feeding after such trauma. And I've killed hundreds of deer with everything from a 22-250 to a 7mm Mag to a bow. The reaction and results are identical regardless of weapon. Never seen one get knifed and belly back up to the buffet though. But hey, if you guys say you've seen then who am I to argue?
