I wont paint as rosy a picture as some on here, you didnt mention that there was much blood on the arrow so Iwould not benot so certain of a liver hit, much less lung. No stomach contents.....I am thinking sincehe is a buck, and it is that time of year... His stomach (in theory anyway

) would be mostly empty especialy if he was a dominant rutter.
Luck with the finding! No advice to give as i am pretty sure youknow more than me anyway! Most gut hits don't do 250 yards. Hope he is one of those.
