I really can't add anything, but would emphasize a couple. Don’t be in a hurry. There are times when pushing a deer can help get them, but I have never had one of those times. I had an arrow deflect off a limb and gut shot deer years ago. I let it go and never following it until the next day. It only went about 60 yards. I have seen many lost from trying to track them too soon. The same goes for a one lung. Unless you hear or see it fall give it a lot of time unless heat or rain forces you to move on it.
I am a two lungs and down in 100 yd. shot taker most all the time. However, I have had my challenging hits. I have gotten a little lax and tend to get on them fairly quick. That finally caught up with me this year.
I shot a huge old doe opening weekend. She was quartering a little more than I like, but I thought it was a good shot. I thought I heard her go down. I shot her early so I sat late in the morning to see if I could arrow another one. When I got on her track it had been a couple hours. I had good blood and a pass through. I tracked her about 60 yd. I was watching ahead, but didn’t have an arrow ready. I got to a point with some brush on one side of me and there see was off to my side. She did a J and went down. I took one more step and her head was up. Before I could get an arrow ready she was up and trotted off. I backed out. The hit looked good and the blood looked good so why was she still going I though. I gave her 3 more hours. When I took up the trail again the blood disappeared very quickly. I marked, crawled, checked all the side trail, but continued on the most likely track. It was partly a low green grass area so no tracks, anything to rub blood on or turned up leaves to follow. On hands and knees I finally found a drop. Then a ways farther another. Finally I found where she went into heavier cover, and I had a a little more blood on some tall grass. This time I was ready to shoot when I eased into the cover. I caught a flick of a tail when I was a ways in. I moved a little closer and could make out the deer. She was still alive and close but no good hole for a shot. I backed out to regroup. It was over 6 hours after the shot. I got around to a better wind direction with what looked like a more open are for a shot into where she was. I waited a while longer staying close, but the rail was on the way. Finally I worked in. I heard a little rustle in the cover at one point. I was ready to shoot, but she didn't get up. I finally got in for a shot, but she was done. When I opened her up I found the arrow hit back a little more than I thought and punched a couple inches into the liver, cut lungs, nicked the heart, and came out low behind the opposit leg. She lasted over 6 hours. She was big, old, smart, and tough. Her total travel distance was only about 200 yd. I am convinced that she was able to last so long only by shear will and the fact she bedded quickly both times. This old girl had a huge scare on her hind quarters from her tail, arund her ham, down the back of her leg and with several off shoot cuts from the main cut. Also a 2” opening in her hide below her anus. I am sure that was not her only injury and she learned to survive.
I remembered a few things I had gotten lax on. Wait as long as you can. Watch out for a turn when trailing up and go slow checking the cover well before just waking in. Be ready for a follow up shot.
