Our customers often ask us two specific questions about ammo: Is it good for an AR-15? And is it good for self-defense? Well, when we’re talking about Winchester Defender 5.56x45 ammo, our answers are always “Absolutely!” and “You’d better believe it!”

This cartridge has a bonded soft point bullet. It is engineered to expand very rapidly in soft tissue making it well designed for self-defense purposes.

The bullet’s bonded core and jacket resist fragmenting apart after striking soft tissue at high velocity. That means they retain the weight necessary to penetrate deeply. And penetration is even deeper thanks to Winchester’s Extruded Solid Base, a design which also prevents deformation during ignition to promote greater accuracy.

This cartridge’s bullet is heavier at 64 grains. A barrel twist of 1:8 is best for long-distance shooting with a 64 grain bullet, but either a 1:7 or 1:9 twist barrel will prove more than accurate enough for the distances you’d cover during home defense.

Brass case. Non-corrosive primer. Clean-burning propellant. Nonmagnetic bullet. Winchester’s Defender ammo is expertly loaded to suit the demands of law enforcement professionals. You will enjoy real peace of mind that you can handle a life-threatening home invasion when your AR’s mag is full of Winchester Defender!
