20 Rounds of 170gr JHP 10mm Ammo by Winchester

A man who carries a 10mm Auto pistol for self-defense is not a man who likes taking chances. He would neutralize the threat with definitive firepower; the very reason why he also needs definitive defensive ammunition.

Let Winchester arm you with the power of USA Ready Defense. It is as good as the Big W can load it, and has match-grade primers and strictly controlled propellant charges to show for it. As with many other premium defense rounds, this ammo’s cases wear nickel plating. It reduces friction inside the pistol, resists corrosion resulting from exposure to humidity, sweat and chemicals, and makes the ammo easier to see in low lighting.

This round’s 170 grain bullet doesn’t just hit hard. It also expands wide, and it does so reliably in the event that a barrier intercepts it before it reaches the threat. Inside the JHP’s nose cavity sits a rigid Hex-Vent, which effectively walls off debris while simultaneously permitting entrance to soft tissue. That makes terminal expansion less a matter of chance and more one of certainty!
