Migra Ammunition Steel Waterfowl Stack Load Features The Migra Steel Waterfowl Stack Load combines #2 and BB steel shot in a single 1-5/8 ounce payload engineered for consistent bulk density and uniform patterns. This combination shot approach gives waterfowl hunters coverage across both close and extended range shot presentations without switching shells mid-hunt. Manufactured in small batches the load uses no fillers relying instead on carefully selected shot combinations for reliable patterning. A muzzle velocity near 1425 fps keeps the payload moving with enough energy for dependable terminal performance on ducks and geese. Built on a high brass plastic hulled shotshell this load is sized for the 3.5 inch chamber found in many waterfowl-focused 12 gauge shotguns. The patent-pending shot combination technology behind this load is aimed squarely at increasing kill ratios in the field. Hunters chasing mixed waterfowl species benefit from a shell that adapts to variable range conditions in a single load. Migra built this Stack Load specifically for hunters who want fewer shell changes and more consistent results in the blind.
