It usually takes a liver shot deer a while to die. You don't want to go chasing after them right away. Let them alone to go bed down somewhere an bleed out. I usually don't go looking for blood for at least a 1/2 hour unless I see him laying there dead. We had to leave one overnight once so we wouldn't keep bumping him and making him move further away. In the end he was only 100 yards from where he was shot. He would have been miles had we pursued him that night. It was cold so his meat was still good in the morning.
