Interestingly I watched a shotgun video shooting pigeons, sending the dog out to retrieve and bring it back, 9 times out of 10 the bloody things were still alive flapping their wings when the dog dropped them. And no it was not nerves.
EVERYONE has misplaced shots now and again, so many small factors can throw that pellet mm off target causing a not so pleasant death but I can see Davey point.
Don't put pics up and talk about it like its something that happens all the time, you could have refrained from posting this topic.
