My son shot a nice 7 point on youth day. 16 yds. 18 feet up. Shot a little back and high. Followed blood for 250 yds. The buck bedded up and after that, nothing. We found the back half of his arrow covered in blood. The blood was dark and high on the weeds. At least 12 inches of the arrow still in the deer. No sign after 3 hours of looking. Thought?? Thanks.
