The award-winning 243 Win Trophy Copper is a new copper, rifle bullet from Federal Premium . A tipped bullet cavity provides hunters consistent expansion across a broad range of velocities, while the grooved bullet shank increases accuracy across a wider range of firearms. The copper-alloy design achieves up to 99% weight retention even after the deepest and most aggressive penetration and expansion. Its nickel-plated case prevents corrosion and aids in easier, faster extraction from the chamber.
