Hornady Traditional and FMJ bullets are engineered for exceptional performance with their rugged AMP (Advanced Manufacturing Process) bullet jackets. Unlike the thin-plated full metal jackets used by other manufacturers, which can easily distort, break or separate upon impact, the Hornady AMP bullet jacket is designed for superior durability. With virtually zero tolerance for concentricity and near-zero variation in wall thickness, these bullets penetrate targets reliably and consistently, without deforming or breaking. Whether you're in the field or at the range, Hornady's FMJ bullets offer unmatched accuracy and integrity on impact.
