RE: how long ' till the meat spoils?
I agree with rcd567. Everything depends on when the animal dies.
It almost sounds like a single lung hit and if so the animal could survive but from the blood loss you describe, I doubt it. I wouldn' t think the animal is too far from where you stopped. Remember two things: get on your hands and knees when the trail gets scarce . . . things look a lot different from that perspective and most animals are lost because the hunter gives up too soon.
