I have this idea...
(my friends Matthew, Dave, and I, that is, all of whom now own 12 ga shotguns) where we'll have the shooter face away from the targets while they're being set up, with the magazine tube loaded, saftey off, chamber empty (cruiser ready). Then, we'll set up a certain number of targets (depending on the shotgun's capacity) behind his back, at varying ranges, but all in his field of view (though some will be at the edges). Then, once the setup guys are safely out of the way, we'll yell "go!" and time the shooter with a stop watch, to see how long it takes him to acquire and knock down all of the targets. I figure practicing that enough will eventually give us instinctive target acquisition and point shooting skills.
