What amazes me is the amount of shots taken at deer on the TV programs that IMO are way too far back. They never show the tracking job except for the last couple of yards - and its always dark. So its pretty obvious that they wait a good while before tracking. Waiting is always a good thing regardless of where the animal was hit (unless you actually watch it drop). You should resist the temptation to go after it immediately or only after a short wait. If I don't see my animal fall, I wait at least 45 - 60 mins for a heart lung shot. Four hours for a liver shot and 12 hours for a gut shot.
