Hornady Ammo Critical Defense 44 Special 165 GR Flex Tip Expanding (20)       Since their inception, conventional hollow point pistol bullets have performed well, but have never delivered 100% reliability, especially in self-defense situations. The patented Flex Tip® technology used in Critical Defense® ammunition eliminates the clogging and inconsistency that often plagues hollow point bullets. Hornady® achieved this by using the same tip material used in LEVERevolution® ammunition.   All Critical Defense® ammunition is loaded in nickel-plated cases for increased visibility in low-light situations. Premium low flash propellants deliver proven performance, even in very short-barreled handguns, and won’t disrupt your vision. Reliable expansion and dependable terminal performance can be counted on for concealed carry and personal protection
