Hornady Traditional bullets are built with a rugged AMP bullet jacket (Advanced Manufacturing Process) that clearly delivers better performance. The thin-plated jacket offered by other manufacturers is easily distorted and often breaks or separates when the bullet impacts the target. The Hornady AMP bullet jacket features virtually zero tolerance for concentricity and near-zero wall thickness variation, punching through targets without deforming or breaking. On impact, the bullet is forced to open up and expand, resulting in less penetration but greater damage due to the larger diameter of the now expanded bullet. These are primarily used in hunting varmints, target shooting and personal defense. This is not loaded ammunition.
