My opening day FAIL!!!

[JLS]

You are aiming too high and too far back.  Ideal aiming spot is directly in line with the front leg, 1/3 of the way up the body.  You likely hit liver and/or guts, hence the rear-up reaction.  They won't bleed much, if at all initially from a high and back shot, but will die.

You only looked for an hour after a solid hit to the goods Did it get dark, or was it buck fever and you think you heard a thwack. I know I am not the only one thinking the same thing here. Anyone that has hunted long enough knows what it feels like to wound an animal and not find it. Only looking for an hour, that's the real fail.

If you are back in that area again next weekend I would look for birds anywhere within a mile of where you shot at the deer. 

My first archery buck was the result of a deflected shot off of a sagebrush limb and I hit it high and back.  I had seen the buck with the arrow sticking out and knew I had made a marginal shot.  I waited an hour or so and then went to track it.  No blood, no hair, no anything.  I knew he was a dead deer walking and notched my tag.  I went out every day before or after work looking for him.  Day 2 I found my arrow, I found him day 4 by the coyotes and birds.  He was close to 3/4 of a mile form where I originally shot him.  He was tucked into a tall patch of dry grass and I must have walked past him a dozen times in the four days I spent looking for him. 

Judging by your description of the buck's reaction you hit him hard.  He would not have reared up and fell over naturally.  Please go back and check the area out again.  I would almost guarantee that he is laying dead out there somewhere.  My

If he stood up on hind legs like Silver, My guess is a brisket hit. He may not be dead. Worth another look around anyway. Only time I've seen a deer do that, the bullet hit low.
