Tonight start off perfect. My 9 year old daughter and I took our first deer hunting outing together with my cross bow. Just before dark three does came in and one was broad side, very slightly quartering toward me and 25 yards. When I shot it hit her hard and I heard a pretty loud crack. She instantly fell and for about twenty yards she was flopping and plowing with her chest. My first instinct was maybe I hit front shoulder. I could not see the bolt in her as she flopped towards the woods. After she went out of sight I went and found the bolt. To my surprise it was a pass through shot, blood all the way up and one of the fletches was peeled back. At first I didn't notice but soon realized my Grim Reaper was not open, and it had hair crammed down into the blades like they did not open. The way she was plowing I was sure her front shoulder was destroyed but I don't think I would get a complete pass through going through the shoulder would I? My only thought is the bolt his the shoulder and then glanced straight down. Just a guess but not sure. There was not much of a blood trail. About 10 minutes into the track in the woods it was dark and my daughter was getting scared so I backed out and am going back in the morning. It was in the high 40's when I shot and supposed to be in the low 40's over night. Once in the woods it appears as she was up because the leaves were not all disturbed like she was on her chest. I heard nothing but good about Grim Reapers and that is why I chose them. I hope it wasn't a mistake. After taking these pictures I checked and the broad heads open with little pressure as they should.
Any other thoughts on what might have happened?
