I've noted that those shooting rifled bores strive to have "instant kills", bowhunters are just happy with finding a kill after tracking it and not having to take a second shot, shotgunners talk the talk of quick kills but the nature of the shotgun is that it is often a wounding weapon. I don't know anyone I've hunted alongside with a shotgun for long that hasn't wounded regularly with one. I believe it's not only the nature of the shotgun, but of "shooting flying" when considerations of all the variables to hit a flying target are put in the mix.
