So I hunt in south jersey on a privant 40 acres. This morning, I took a shot at a buck that was behind my stand, at about 30 yards. Since it was behind my tree, I had to kind of bend out and aim out to the side. The deer was standing in mud and water, with a lot of thicket anf thorns in the area. It was about 6:10 when I took the shot, so early shooting hours. I believe my arrow went under the deer, but I am not 100% sure. I shoot a pse vendetta xs at 53 pounds. The deer took off, slowed down, looked back at me, snort wheezed, and hung in the area acting very curious and concerned. Didn't appear to be shot. Him and the 5 does ran off, and later when I went to track him, I could not find my arrow no matter how hard I searched. Absolutely no sign of blood whatsoever. So deer seemed fine, no arrow, no blood. I have up the search after about 3 hours. Can you guys help me out, give me some input?
