I fail to see how Doverham concludes that the eye and the pointing hand is in a different relationship when using a shallow receiver gun than when using a deep receiver gun. Assuming a similar forend configuration and similar drop of comb and heel, the relationship should be identical whether shooting a Boss or a Merkel. Some deep receiver guns handle like crap, but it isn't because of the basic design, it is because of the configuration, especially the grip configuration, of the individual gun.
