It’s not a hard task to concentrate all your gun’s firepower on a single bird when there’s but one set of wings before you. Ditto for the grouse’s twittering cover mate the woodcock, which most often also prevents itself as a lone target in these Northwoods uplands. Besides, any gunner knows that his duty is to dispatch a bird decisively, and a second shot on a wing-tipped game bird is a subconscious “must” before ever considering shifting to a different one in the air at the same time.
