This Saturday I had a real nice 8/10 pt typical come around the stand and stop at 12 yds. It was 5min left of legal light, cloudy day, and I am in the woods under the canopy. Needless to say it was pretty dark. The little shooting lane he stopped in was no more than 24" wide, he was quartering towards me. I thought I have about 2min to make this shot before I can no longer see my pins, so I let the arrow fly. The arrow hit right inside his right shoulder and it made a good thud noise, not a smack of shoulder blade, but a cavity thud, he fell to the ground and rolled on his side, got up, and hobbled into super thick grass 8-9' tall where you cannot see more than 5' in front of you. I felt 100% confident in the shot and the reaction of the deer. I heard where he stopped about 35yds out and it sounded like he crashed. Gave the deer an hour, 3 guys came to help me track, we found no arrow (assume still in the deer) and no blood at impact point. We found minor minor muscle blood to where I heard him crash, after that nothing. We backed out, it rained that night, came back and 5 guys walked the entire grass field with no sign of the deer and again no further blood trail. Other than not take a quartering towards shot, and wait for broadside shot, I believe there was noting more that could have been done. Where was this deer hit? I cannot imagine this deer surviving with an arrow in him. It just seems like a very unlucky circumstance. 3 years of bowhunting, 3 deer shot and never found, no deer recovered with a bow to this point. It really is becoming very frustrating.
