Designed for fully rifled barrels, Hornady American Whitetail Slugs are loaded with 325-grain Hornady InterLock bullets. A hollow point serrated design initiates rapid expansion upon impact, and a tough, lead alloy core is lethal out to 200+ yards. The rigid polycarbonate sabot ensures accuracy and the end result is an accurate delivery system for a tough shotgun slug capable of taking the biggest midwestern whitetails. It has an InterLock ring that locks the core and jacket together to deliver controlled expansion combined with excellent weight retention, energy and accuracy.
