The Remington Hypersonic Steel line of shotshells was designed to be the world's fastest-flying hardest-hitting shotgun shell for waterfowl hunting. Not only did Remington meet these expectations but it exceeded them with the high-powered and versatile Hypersonic Steel shotgun shell. These shells deliver unmated velocity combined with the highest ever down-range pattern energy ever seen in a waterfowl shell. Not only does the Remington Hypersonic Steel line of shotshells take shotshell performance to a new level but it also gives you the ability to drop more birds with fewer shots than ever before.
