Hornady InterLock Bullets 45 Caliber (458 Diameter) 300 Grain Hollow Point Box of 50

hornady critical defense bullets are built with a rugged AMP® bullet jacket (Advanced Manufacturing Process) that clearly delivers better performance. The thin-plated full metal 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. This is not loaded ammunition.

hornady critical defense has established a new standard of performance for self-defense ammunition in compact handguns. Its Critical Defense loads offer a good balance of penetration and expansion, even when first passing through heavy clothing. … Hornady claims this tip initiates expansion and the ammunition is supremely reliable

Critical DEFENSE® handgun ammunition is ideal for backup weapons, off-duty carry or for those serving in executive protection, undercover operations, or any dedicated close quarters situations. Critical DEFENSE® provides controlled expansion while reducing the potential of over penetration.
