Lead free copper 20 Rounds per box The G2 Research® RIP (Radically Invasive Projectile) is as devastating as it looks, creating 9 separate wound channels that absolutely shred soft targets. It penetrates 14-16" through light or heavy clothing, and defeats all known barriers, including sheet metal, sheet rock, windshields and plywood. So it really is "the last round you'll ever need." Offers maximum expansion through light or heavy clothing 13.5″– 14.5″ of Penetration 2″ Groupings at 15 yrds 9 Separate Wound Channels Solid Copper / Lead Free 5.5″ – 7.5″ Diameter Spread Precision Machined Defeats all known barriers such as sheet metal, sheet rock, windshields, plywood, heavy winter clothing. 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 which gives it the ability to not only penetrate deep into a target but also fragment in fluid. Upon entering a gel or fluid the petals break from the base and create individual wound channels as the base continues on course. This penetration and separation delivers not only a maximum shock wave but wound path as well. 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. The surgically designed trocars offer better barrier penetration thus maintaining a higher velocity when hitting a target, transferring more energy into the target. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases. Made In The United States of America  Be sure to read our shipping policy.
