I have shot and missed and was able to work the same bird from a different location by changing calls , 2 hours later. I also shot one and he got away. I was sick. Less than a week later , about 100 yards from where I had that happen , I killed a bird that had pellets in it. Can't be positive , but I believe it was the same bird from earlier in the week. Keep after him. It's a good chance you will get another shot.
