Made of tungsten-nickel-iron alloy, Remington® Premier® Hevi•Shot® isn’t just another non-toxic substitute for lead, it’s the first and only substitute that actually performs better than lead. With increased density and more energy over virtually all distances, Hevi•Shot® literally blows steel away. It’s 10% heavier than lead and an amazing 54% heavier than steel, resulting in higher pattern energy and greater lethality at all reasonable distances.
