Most ducks are missed from behind, but the unprecedented velocity of remington hypersonic steel compensates for this by reducing required lead by 8 at 40 yards (about a full body length) on a duck flying at average speed.It puts more steel shot in the head and neck for quicker kills and fewer misses.With the highest velocity and downrange pattern energies ever achieved, hypersonic steel takes lethality to new heights, to a level of terminal performance where more birds drop with fewer shots at the farthest reaches of your abilities.Application: WaterfowlGauge: 12 GaugeType: SteelLength: 3.50"Ounces: 1 3/8 ozShot Size: 4Muzzle Velocity: 1700 fpsRounds Per Box: 25Boxes Per Case: 10Shot Type: Zinc-PlatedHazair: YesAmmunition cannot be shipped to a P.O.
