I think that's a good looking pattern even at 20yds. POI comes down into the center of that 10" circle and you're looking at a good, even 8" pattern. That's a fuzz tight but not much at that range. Wouldn't want to sacrifice widening what you've got at 40 to gain much at 20. At that closer range just drop POA on the live bird to first feathers like the true center of that target and there won't be as much movement as the head. With that 507 he's toast.
