Gatsby I am certain you are not an %%%%hole. However your Casull etc are presumably fully rifled, high velocity weapons whose ballistic performances/characteristics are a whole lot different to a shotgun slug. I would love to see myself proved utterly wrong but I won´t be doing it myself as I can´t shoot iron sights anymore past much over 75 yards, aperture (ghost ring)a bit further maybe, best,
Mike (I mean all previous comments in the best way, no slight intended to anyone of course)
