Ishot a great buck this morning at 7:30am. He was directly downwind of me before I had an open shot. He was quatrering to me when I shot


I know I know wrong move on my part. He was getting ready to bolt so I took the shot.I hithim directly inthe shoulder but not really high or low.My arrow went in about 6 inches and came out after 30 yards of him running. He ran about 50 yards and stopped behind some brush so allI could see was his rack. I picked up the binos and by that time he was gone up the hill. I waited until 1:00pm to start the tracking and found blood WITH BUBBLES (nota lotbut definitely some bubbles). So I was thinking I got one lung. We trailed him for about 100-150 total yards and the blood trail seemed to get down to just drops. We grid searched until dark and no buck yet. Going back out tomorrow (I have all day to look).
Any other experiences or suggestions for me. I have shot a few other bucksdirectly in the shoulder with only 6 inches penetration and found them within 80yds.
