Not everybody’s idea of “home defense” is to fire two negligent discharges into the air from a double-barrel shotgun. Some of us think it might be more effective to actually shoot the ammo *at* an invader. And for more and more people, they’re foregoing the shotgun and instead reaching for an AR. An AR-15 for home defense? Why not? Powerful, low recoil, easy to aim, high capacity, easy for smaller shooters to handle. It may not be everyone’s choice, but it is the most popular rifle sold. Surplus military ammo, though, is probably not the most suitable round for home defense. In this video, ShootingTheBull410 takes a look at Winchester’s PDX1 223 Defender; it’s purpose-built ammunition designed specifically for the modern sporting rifles and for personal defense use.
