RE: best shot placement on a deer
Kinda reminds me of a retarted buddy I had who shot a deer in the neck, saying it was the only shot he had. Deer ran off with an arrow sticking in his neck, never recovered. I no longer hang out that retarted kid...mainly because he does retarded things.
Shooting farther back wouldn't have helped you any. You would have totally missed the vitals in that regard and ended up with a mile long track with a gut shot.
Find yourself some anatomy photos of whitetail deer, elk, horses or anything with four legs...they all are pretty much constructed the same...study those pictures...then think three dimensionally. Where will the vitals be in relation to a quarter too shot, a quarter away shot, etc. We live in a 3-D world...you can't aim for the 10 ring on quartering shots because you won't put it down quick.
