If you shoot him in the afternoon I'd say wait until AM. If you shoot him in the morning, I'd say wait until mid afternoon. Of course there are forces which would make me change that, but that has to be decided at the time. If you gut shoot one he's going to need at least 8 hours. Otherwise you're going to get him up when he would have stayed put, probably no more than 200-300 yards from your stand. It's going to be a tough enough track as it is with minimal to no blood a lot of the time. The further out you push him, the more likely he'll be lost. Let him be and let mother nature take her toll for your bad hit. I'd say it is almost luck to find most gut shot deer as it is without adding a few hundred more acres to the search grid. Chances are the blood will stop real quick unless you get extremely lucky and hit an artery. The object is to keep the search grid as small as you can. That means waiting and getting out of there and keeping others out if you can. If you're unsure of what you hit you must wait. The evidence on the arrow will tell you a lot, but it's not a definite for a lot of people. Sometimes we see what we want to and not what really is. Most deer I shoot I have a pretty good idea of what I got. When I do I just take a few moments to calm down. I then usually gather my gear up and sneak out quietly to deposit excess gear in the truck and then go track. That usually gives more than enough time for well hit deer. But, most well hit deer go down within site or hearing range don't they. After I hit the ground I look at the arrow. That tells me a lot. My last deer was drilled dead center, in and out. I was shocked he made it 100 yards.
