A new polymer-copper blended bullet made by PolyCase Ammunition and licensed by Ruger promises to deliver ultra-high velocity and superior terminal ballistics for personal protection.
According to Ruger, the distinctive bullet profile transfers maximum energy to the target by fluid dynamic effect. The non-expanding Ruger ARX exploits the bullet’s velocity to redirect energy laterally via flutes in the bullet ogive. This effect results in stopping power and terminal performance that rivals that of many expanding handgun bullets, they report.
ARX Self-Defense Ammo
The design of the Ruger ARX allows it to feed like a round nose yet still transfer energy to targets effectively over a wide range of bullet velocities. The ARX penetrates many barriers without deformation and penetrates through clothing without clogging and degrading terminal performance.
The Ruger ARX ammunition utilizes injection-molded copper/polymer matrix projectiles. Unlike traditional bullets, this unique material can be molded into complex shapes like the ARX bullet configuration. These lightweight bullets are launched at high velocities and achieve very high energy levels, but at nominal or even reduced recoil levels—while reducing the loaded weight of firearms and spare magazines. The copper/polymer bullets fragment upon striking solid backstops, Ruger said.
Currently, the ammo is available in .380 Auto and .45 ACP. The .380 is said to be clocking 1,315 feet per second (fps) with a 56-grain bullet—putting about 215 foot-pounds (ft.-lbs.) on target. The .45 ACP does about double that, with its 118-grain bullet at 1,307 fps for 448 ft.-lbs of energy.
According to Ruger’s website here, 9mm and .40 S&W will be available soon.
