It sucks DJfan I hope you didn't stay up too late worrying about this. As I sit here 2 hours before sunrise I am hoping you have a day planned of going back out to look for this deer again. 1 hour isn't enough time to look for a deer you didn't recover. You should also take your rifle and a target to see if something happened to your gun. This is what i would be doing if I where you. I will be offended if you are online the morning after typing about it when you still have things you could be doing.

I've shot many whitetails with cartridges far weaker than a 30-06 where SuperHunt pointed and, if I didn't get a good blood trail to follow, the deer have dropped with a broke spine or died close from blood suffocation with blood dripping out the mouth.

If the above didn't happen I either missed, hit where I didn't think, or been walking by a dead deer. Good luck and keep us updated on what you find.
