I shot a very nice buck last Saturday with a muzzleloader. It was very early and after the shot, the smoke hung right in front of me and I did not see the bucks initial reaction. As the smoke cleared, I seen him running and assumed I missed. He ran about 40 yds and then started walking slow and all the sudden he just fell over. He didn't lay down as deer normally do, he fell over sideways. He was in an open field. I looked through scope and couldn't see him after he fell in the high grass. So, I set down to gain my composure, and assumed I had a big buck down. After about five minutes I glass back at the buck and he has his head up. It is wide open field and I am uphill from him so I just decided to sit and watch hoping he would expire. After another five minutes or so he stands up but does not move. I tried to shoot him again but at this point he was about 250 yds and I missed. He just stood there. He was a little hunched up. He then began walking very slowly and I decided to move over into some cedars and work my way toward him to try and get a closer shot. As I weaved through some cedars, I jumped a couple doe that I didn't know were there and they ran toward the buck. At this point I couldn't see him. I am thinking they got him moving. I went down to where he fell and there was just a little blood where he fell. I tracked some sporadic blood over to a fence which went into a thicket. I heard a deer walking slow in the thicket and decided to back off. I waited about two hours and crossed the fence into the thicket. The blood trail got a little better after he went through fence but dried up about 70 yds which is where I last heard a deer walking. The blood was darker red and I am thinking liver shot. I searched some of the thicket with no luck. I couldn't go back Sunday and had to work this week. I was hunting out of town. I plan to go back Friday and look some more. I had really give up Saturday afternoon, thinking he would live. But after reading about liver shot deer, the bucks reaction seems to fit with a liver shot. If that's the case, he should be dead. Based on the info I have given, what are your thoughts?
