RE: shot placement
But there are good killing shots at the vitals other than straight broadside. There are websites and publications that give you targets at various presentations - I can't refer you directly but maybe someone else can. There's a lot of places a well aimed bullet can get through to the vitals or spine without hitting guts or messing up too much shoulder meat.
What I try to keep in mind is where the heart lungs and spine actually are and then decide if I can get a shot at that spot, aiming "through" the deer, at the angle he's standing. But I also am very conservative and always opt on the side of not shooting if I don't think I have a pretty good shot.
