Why are Long Beard "specific" chokes entering the market? Is it that WLB shells don't like ported or wad stripping tubes? I am aware that a least one choke company specifies their product not be used with Fed. Flite control. I haven't heard of a company specify this in regards to WLB. shells. Is a Long Beard "specific" choke going to pattern better than my much touted SSX in my Mossberg 835? Are these "specific" chokes doing away with wad stoppers? Thank you for input
