Remington HyperSonic, 12 Gauge, 3, 1.25 oz., Steel, #4, Lead Free, 25 Round Box, California Certified Nonlead Ammunition 26777 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 - without changing the way you shoot. 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. And only Remington harnessed the wad technology to do it.
