It is irresponsible if hunters don't consider limits of skill, gauge, distance and prey. After 75 years of duck and geese hunting, I've found the knack of responsible shooting from a blind, as you have for yours. The irresponsible part of your post to me is wounding a bird that can't be found. All birds will be found with a dog. I've not retrieved exactly three birds in my life: when my Lab couldn't get a dead one that slid under the ice, another called in because he would have drowned from exhaustion chasing a diving bluebill in white-caps, and one that set its wings a kilometre way and dove into the bay; retrieve impossible.
