If it was a shoulder hit it is probably a dead deer but almost unrecoverable imo. I hit one of the biggest bucks of my life in the shoulder the last day of Michigan's archery season years ago in a snowstorm. By the time I got help to start tracking the trail was covered with snow. I spent 2 days looking. The next weekend a buddy had his kids up and I offered them $500 if they could find the deer. Never found it and the deer was never seen agian after being the talk of the town for years. I am sick just thinking about it. It took 3 seasons to get a shot at him and I fugged it up. Mainframe 12 with junk everywhere. Probably a 250-300lb deer. I know 300 pound deer are rare but I have killed and seen plenty of dead ones weighed. This thing was a TANK. My guess was 7.5 years old.
Anyway Nate I know how you feel, sometimes it just happens. Practice is great but shit can go wrong in a hurry with a live animal in front of you. Shake it off and get back after them.
