Polycase Inceptor ARX Handgun Ammunition combines cutting-edge lightweight, low-friction polymer cartridges with the ARX self-defense projectile. The non-expanding ARX is injection-molded from a specially blended copper/polymer matrix that is designed to be tough enough to penetrate soft targets and tissue. When it encounters tougher barriers, it is designed to break apart to reduce the risk for collateral damage due to over penetration. Even the heaviest clothing barrier has no effect on the terminal performance of the ARX bullet.
The Inceptor ARX penetrates straight until it encounters soft tissue. Upon entering soft tissue, the unique grooves in the nose harness the rotational energy of the bullet during the initial six inches of penetration. Through this lateral force dispersion, the projectile produces maximum terminal energy to the target. As the bullet penetrates, it tumbles in a controlled, predictable fashion that delivers very consistent terminal performance. The flutes in the nose of the ARX bullet harness the gain in kinetic energy accrued due to the increased velocity of fluid through the constriction designed into those flutes. Fluid passing through the ARX flutes travels between one-and-a-half to two times the velocity of the bullet. In soft tissue, the Inceptor ARX is designed to penetrate 12" to 14" every time.
