I shot a buck the other night from my tree stand. The buck was walking towards me at a somewhat 45 degree angle. The shot distance was 15 yards. My arrow entered right in front of his shoulder blade in the neck slightly above dead center and exited dead center in the opposite shoulder blade. Complete pass through with a 4 blade slick trick. After the shot he ran 20 yards and froze, blood poured out of his neck really good and sub par out of his shoulder. He then walked 40 yards started to rock and then bedded down. I thought he was done but he got back up and walked 20 yards bedded down for a couple minutes and got back up. He did this a total of 5 times before I slowly backed out. I gave him 18 hrs and came back to look for him. I followed descent blood for 60 yards after I last seen him but lost his trail. What do you guys think?
