Winchester USA Ready Defense Ammo
Winchester's USA Ready Defense ammunition features Hex Vent technology, a rigid polymer insert in the hollow point designed to prevent plugging and ensure reliable expansion. This technology aids in barrier penetration and allows material to flow around vents for hydraulic action. The ammunition is offered in 9mm (124gr), .40 S&W (170gr), and .45 Auto (200gr), with lighter bullet weights chosen to achieve higher velocities from shorter barrels for consistent expansion. Packaging includes a window to showcase the Hex Vent technology.
