The wife took a 20 yard shot at a doe while we were in the ground blind tonight. I watched it hit the deer right on the shoulder and the deer dropped right there. After about 30 seconds to a minute, the deer stumbled to it's feet and went 15 yards then back down. Then off in the woods. Found the arrow at impact site, broadhead(G5 Montac) broke off inside. I suspect one lung hit. How long to wait? It's been over two hours already since the hit.
