Designed for fully rifled barrels, Hornady American Whitetail Slugs are loaded with 325-gr. Hornady InterLock bullets. The InterLock ring locks the core and jacket together to deliver controlled expansion combined with excellent weight retention, energy, and accuracy. A hollow point serrated bullet design initiates rapid expansion upon impact. Serrated lead core and jacket allow for even expansion at low velocities. The lead alloy core is tough enough for the biggest whitetail. The rigid polycarbonate American Whitetail Slug sabot has an exclusive buffer disc combine to open uniformly without compromising accuracy. Box of five slugs.
