Posting this for my son, here's a brief rundown of what happened, full story on a separate thread.
We watched him bed down in a canola swath, it took us 1-1/2hrs to stalk up 560yds right up to about 15yds away. I got Hunter to come to full draw then I rustled the canola to stand the buck up. As soon as it stood up Hunter let him have it right in the lungs. It was pouring rain the whole time.
