I agree, Ray, and said pretty much the same thing in my post, though not with your detail.
The big problem with most hunters, however, is that they won't do the same kind of practice. However, most shotgunners (especially ruffed grouse hunters) take to it pretty easily.
I will also note that a few years ago I won a timed target-shooting event on Cape buffalo targets with an iron-sighted rifle, with 3 hits in the fastest time--and almost all the otgher shooters used scopes.
