If you're plinking for practice, go ahead and burn through your "good enough to go pow" ammo. But when it comes to an "every second counts" self-defense situation, there isn't any such thing as ammunition that's "good enough." If you're defending your life, you need the very best, and the latest salvo from Winchester Ammunition is just that. It's called USA Ready Defense, and it'll be ready when you need it most. The company bills it as the ideal combination of stopping power, penetration and reliable expansion ... otherwise known as the best of the best. 

When we talk about "stopping power," we're referring to "terminal ballistics," which is simply the transfer of energy from firearm to target. That transfer needs to be effective even when the target (the attacker) is wearing heavy clothing. Obviously, that's of particular interest during the cold months. USA Ready Defense ammunition features a distinctive Hex-Vent bullet design that allows that to happen reliably. The Hex-Vent is a rigid insert nested inside the jacketed hollowpoint cavity that keeps clothing from blocking the bullet's ability to expand once inside the target.

What that means for self-defenders is that you can load your carry pistol with the appropriate ammo, and trust that you'll get the consistent performance that the situation demands. Fired through common personal defense pistols, the 9mm Luger +P 124-gr. variant demonstrates 12" penetration with 95 percent weight retention.

Along with sledgehammer-like impact, USA Ready Defense ammunition achieves high accuracy and trusted reliability thanks to its Match Grade Primer and lot-controlled loading techniques. In fact, the individual ballistics data for each lot of USA Ready ammunition are available online at Winchester.com/USAREADYINFO.
