Hornady Critical Duty® .40 S&W ammunition is, as noted, a product from the Hornady "Critical Duty®" line. The Critical Duty® line of ammunition was developed as a response to the unyielding needs of law enforcement officers and tactical professionals, and served to correct the inconsistencies associated with the standard jacketed hollow point projectile. All Critical Duty® ammunition features projectiles that boast superior terminal ballistics ratings as well as nickel-plated cases that not only reduce the risk of corrosion, but improve feeding performance as well. Like all Hornady ammunition, the Critical Duty® line is manufactured in the United States at the Hornady production plant in Grand Island, Nebraska.

The cartridges found in each box of Hornady Critical Duty® .40 S&W ammunition begin with the company's patented FlexLock® projectile. The FlexLock® projectile begins with the company's patented FTX® design, which benefits from the use of a state-of-the-art Flex Tip® technology that is employed to eliminate clogging and other inconsistencies often linked to standard jacketed hollow point projectiles. This technology is paired with an Interlock® band that locks the jacket to the high-antimony lead core to provide for maximum weight retention and unparalleled terminal performance. Additionally, each cartridge is loaded with a stable, clean-burning propellant that not only reduces recoil in light-frame handguns, but also minimizes muzzle flash to protect night vision. The result is a unique projectile that delivers exceptional on-target expansion and uncanny consistency.

It is so good that I have been hearing rumors of it being made a government and law enforcement only ammo! It will expand everytime, penetrate barriers, retain wait and velocity, never get clogged, and its primers are sealed! The wonder ammo for the best price!
