I know that feeling. I took a shot at a nice buck very early Saturday morning. I was a couple of inches too far forward and hit him in the shoulder. No penetration, even though I am pulling 65 pounds and using Slick Tricks. I waited for an hour, and cautiously started looking. No blood, but I know the area very well and was able to follow his tracks in a muddy field. Found the arrow about a half mile from where I took the shoot, broken off right behind the broadhead, with no blood at all on it. No blood on the ground at all. I checked all the usual spots, with no luck. I hope and pray that he will survive and I tend to think that he will, but you just don't know for sure. Still some corn in, and I told the farmer if he comes across him, let me know.
This is the first buck I have missed in several seasons, and it just makes me sick. Hope the feeling goes away so I can get back at it. Right now I kind of feel like packing it in.
