I'm no expert, but I've noticed the deer I've seen act like nothing happened. Gut pile there, quite soon after the shot deer are back there. After my dad shot one this season, he had just pulled the guts out, and looks up to see a big doe watching him. My thoughts have been that the big bucks are smarter though. Maybe that's why they've lived to be old enough to be big.
Again, I don't know anything for sure, just speaking from my thoughts and little bit of experience.
