RE: Heart or lungs?
Lungs............the first deer I killed I shot through the heart.........I was just aiming tight and low behind the shoulder, I think the deer had that leg forward. Got nothing but heart.............it was beutiful.
The buck just stood there for a couple of seconds.......then his kness buckled....he ran two or three tight circles trying to keep his balance.
Once he did, he headed off........ran about 50 or 60 yards and laid down.......he was done when he hit the ground.
With all of them could be like that..........
Lungs leave more room for error........
