I have been hunting them for over 40 years and still had that happen this year. I rushed the shot on a damn good buck chasing a doe. He was just shy of 200 yards and was about to go out of sight but stopped for a moment. I didn't have any support for my trigger side elbow and could not get the crosshairs settled. I thought I could pull it off by timing the trigger pull with the crosshairs crossing his shoulder. I know better but did it anyway. Right thing to do would have been to let him go. Only found some greasy hide and a few drops of blood where he stood for a while at a road crossing. That was it. I looked for about 6 hours even though I knew it was pointless. Still very disgusted with myself for that idot move.
