Federal Vital Shok Trophy Copper Rifle Ammunition -
Tipped bullet cavities offer consistent expansion across a broad range of velocities for devastating downrange performance. Grooved shanks increase accuracy in a wider range of firearms. Polymer tips and boattails increase ballistic coefficient for higher velocity, energy and less drop. The copper-alloy design achieves up to 99% weight retention even after deep, aggressive penetration and expansion. Nickel-plated cases prevent corrosion and aid in easier, faster extraction. Made in USA.
