Ruger® 45 Auto 118 Grain ARX® ammunition is a licensed product made by PolyCase Ammunition and features PolyCase’s patent-pending alloy-polymer bullets, made using the latest in injection molding technology, loaded in traditional high-quality brass. The ARX® SELF-DEFENSE cartridge is the next-generation of personal protection projectile technology due to its range compliant advanced materials, design and exceptional performance. The ARX® is a non-expanding bullet that delivers terminal performance in a completely different way than traditional expanding (hollow-point) bullets. The ARX® features 3 specially engineered arc-shaped grooves which harness the rotational and directional energy of the bullet as it impacts a semi-solid or solid target without expansion, creating massive temporary cavities and resulting in total transfer of energy to intended targets. Due to the bullet profile, the ARX® is “blind” to clothing barriers, even heavy leather and denim. The ARX® thus mitigates several of the inherent disadvantages of hollow-point rounds, such as clogging with debris or clothing, and feed ramp issues.
Ruger ARX® cartridges are designed to function all weapons, including large frame handguns, carbines, fully automatic and suppressed weapons, yet due to the uniqueness of the ARX® bullet it has a low-recoil signature for increased follow-up accuracy in critical self-defense situations. Out of a 4 inch test barrel the Ruger 45 Auto 118 Grain ARX® achieves 1307 FPS muzzle velocity, 448 FT LBS of Energy.
