Watery blood doesn't mean anything? Really..... I guess it does when you have to walk 300 yds. to find the first spot of it though. I have seen deer limping around the woods missing a front leg from a wound the previous season.

Even though he drew blood doesn't mean that that deer is dead. And it is more likely given the fact that he found first blood after 300 yds.

I fleshed a deer's skull out once for a mount that had a noticeable bump over his left eye under his hide. When I removed the hide from the skull, There was a silver object lodged in his skull. It was a headlight bezel from being hit by a car and had been lodged in his skull for about 2 or 3 seasons.

We also where caping a large 9 point late muzzleloader season that had its windpipe severed by an arrow 2 months before. The wound was totally healed over and we found the broadhead and about 2 inches of arrow lodged in the muscle of his neck.

Deer are very tough animals and can survive a whole bunch of things. Especially if you don't hit him where it counts. Sure this deer might die, but given this hunter's description of the blood he found and how long he had to track to find it.... it's likely that this deer is not critically hit.
