Ive been looking at Rhino Ported Chokes, they look rather smart but I dont know of any one who has used them so thought I would ask if any of you guys have used them or are using them ?I would like to know how they pattern, it says on their web site that you can go a size down ? so Im thinking of 1/4 and 3/8 for starters. I would be interested reading anyone's views on these chokes. Rob
