Federal Premium Ultra Steel blends the rear-opening FLITECONTROL FLEX wad with a payload of the best zinc-plated steel, producing extremely tight patterns for even deadlier performance. Available in a variety of standard payloads, as well as loads that feature two sizes of shot: smaller pellets that create full patterns and larger ones that deliver better lethality. Waterfowlers live for those moments when the birds do it right. And in those moments, they want a shell that does the rest.
