Buy G2 Research RIP bullet 45 ACP 162 Grain Radically Invasive Projectile Fragmenting. G2 Research is a premium self defense, and environmentally conscious defense/hunting ammunition manufacturer. G2 Research’s vast understanding of material properties and utilization of complex geometries renders predictable and consistent results. That maximize the effectiveness of its solid copper/lead free projectiles. The G2 Research R.I.P. (Radically Invasive Projectile) features a unique one hundred percent copper petaled-trocar design.  Upon entering a gel or fluid the petals break from the base and create individual wound channels as the base continues on course. In years of ammunition design there has always been a trade off between mass and velocity to accomplish the goal of effective stopping power. G2 Research added a third variable with the patented trocar design. This ammunition is new production, non corrosive, in boxer primed, reloadable brass cases.
