The farmer where I hunt finds deer once and awhile. If they are closer to the road he figures car hit. If closer to the bush then bad shot. He hunts controlled hunt, got a really big buck couple of years ago. It had been hit in the back leg with and arrow. The deer meat was all green and spoiled. It was the walking dead. They cut the antlers off and throw the rest away. So it not just buck shot, it is the shot of whatever. People making bad shots or shots they shouldn't be taking. Lost deer happen, but really shouldn't. I have been luck so far and have found all my deer.
