Federal Power-Shok is hard hitting ammunition designed for exceptional performance in the field. A combination of premium bullets with Federal's reputation for quality results in a hunting round that you can depend on. Power-Shok Copper provides that same consistency in a non-lead, California-legal bullet. Hunters can rely on the one-piece copper-alloy construction and deep hollow-point design. Power-Shok Copper’s hollow-point design expands consistently, creating large wound channels and efficiently transferring energy to the target for quick, clean kills.
