muleskinner - I found a blood smear on one of the vanes. That was the only blood on the arrow.
I did spend a lot of time tracking and looking for him, and I am fairly convinced that he did not die that day. I just hope that he does not get an infection and die later. He was not a 170 incher, but was still a great buck...would have been my second best.
I'll bet any money you hit low and just grazed the brisket. Had you had a pass thru blood would have been on all three vanes. Same exact thing happened to my buddy opening day.
