I think tracking a deer shot with a bow is totally different than tracking a ML shot deer or any gun for that matter. You need hands and knees tracking that can take forever and some people I've tracked with didn't have the patience, they just wanted to skip ahead. I'm not placing you in this catergory I just think some people get too anxious and miss valuable sign by going to fast or starting the tracking too soon.The first hit sounds like a liver which should have been a 2hr wait min. and the second (if you hit where you thought)could have been a high lung hit that might have taken a bit for the blood to build up and hit the ground, but she still could have exhaled some through the nostrils which could have been very fine and easily missed. Another thing, When I first started hunting the first few deer I shot I swore I hit them in one spot and when I found them I was usually off on my guess as to where I hit them. I told my dad once "I know I double lunged him" and when we found him it was a liver shot. I guess the short answer is track slow and don't track too soon, I shot a 7pt Tue. that I heard crash andI was 95% sure that itwas a heart shot and I still waited three hours-- he was still dead when I finally got there. good luck and don't give up.
