Here's a very recent story that may or may not help you in tracking.
My son in law hunts in my back yard on our 20 acre wooded lot. He's been putting out corn, has a trail camera and his stand down there since opener. On Tuesday, just a few days ago, he went out at about 5pm to wait in his stand. He got a good broadside opportunity to get a big doe at about 25 yards and took it. He "thought" it was a good double lung shot. He thought he saw the arrow go into the left side, high in the lung, and exited on the other side so he figured a double lung shot. Actually the arrow went through her, then hit and bounced off the fawn that was behind her. Scared the crap out of the fawn but didn't stick. He took the shot at about 6:30, waited until 7:00, climbed down and found the very bloody arrow, then came up to the house and got me to help him track it. He's way more experienced of a deer hunter than I am, but he knows I love this kind of stuff so he came and got me.
We went down at about 8:00 pm with headlamps on and found lots of blood. I'd say at least 4 spots in the leaves that looked like an entire cup of blood, as well as lots of drops and strips of blood. She ran about 60 yards from where she was shot then we could see her eye shine with our headlamps through the brush. It was too thick to see her body, but we could see that she was alive, sitting down, and watching us about 15 yards away. We were debating what our next step was when she got up and ran again. We walked over to where she was sitting and found just like a tablespoon of blood. Not much blood for laying there with possibly two holes through her for almost 2 hours, but it didn't sound like ran far as we did hear a slight crash. We debated about just going back out in the morning but thought we'd give her a couple more hours at least so we went home.
At 10:30 we decided to go back out. We tracked her at least another 60 yards. Not big cups worth of blood like before, more like a few tablespoons of it, along with some drops, and again we saw her eyeshine through the brush with our headlamps. Still alive and watching us at about 12 yards away. We watched her about 30 seconds when she jumped up and ran again. We heard no crash this time, but we walked over to where she was, and barely found any blood on the ground this time. He was now questioning his shot placement and we thought it would be best to wait until morning.
About 8:00 am the next day we went out again and picked up where we left off. We found very little blood. Just single drops and not many. We tracked her about another 50 yards where she started running straight down a cut ATV trail and found the last drop of blood on a small leaf in the middle of the trail, then nothing. We thought that maybe the shot might have just wounded her and she was long gone, but that maybe she ducked off the left side of the trail somewhere so as ethical hunters, we split up and started wandering around in that general direction. We never saw any more blood but eventually found her, expired, another 30 yards off of that trail.
It was a great double lung shot, through and through, and she still was able to live for over 4 hours and run about 200 yards.
She was a tough one.
Good luck.
