I normally will pass up a head on shot with crossbow. 2010 was an exception. I was still hunting on the way to the area I had planned on hunting. Before I made it to the spot, I heard movement in the brush about 20 yards from the trail. Before I could get in position for a shot, a nice buck came down a trail and hit the main trail I was on about 20 yards in front of me. He bolted back the way he came and I figured he was gone for good. I slowly got up and he was standing just a few yards from where I first saw him, but facing away from me. There was no clear shot at this point so I crouched down and used a buck grunt. This brought him back to the main trail and he snorted and jumped back in the brush. Still no shot. I made sure that everything was ready, checked safety and made sure red dot was on. I grunted again and the buck turned and walked down beside me. When he stopped, there was a branch covering his vitals. I was patient. He took one more step and turned towards me. I knew that he would bolt without giving me a good broadside shot. I shot and when I did, he jumped and was gone. I knew the shot was good, and my confidence in that shot was strong. Three feet from where he was standing I found a spot of blood, a couple more feet and I found a very good blood trail. He ran into a ravine about 80 yards and piled up. He is the second buck that I killed this way with a crossbow.
Some are fast to condemn that shot, but if you know that you can make it, then it is your call. Oh, the arrow was still in the deer. It missed his spine by about a quarter inch.
Tree hugging is okay, as long as you are climbing up to your tree stand
