G2 Research Ammunitions R.I.P. .40 S&W 115 Grain Hollow Point Brass Cased Pistol Ammo 20 Rounds RIP 40 S&W. I.P 40 S&W 115 gr Hollow Point (HP) 20 Bx/ 25 Cs - The G2 Research Radically Invasive Projectile (RIP) bullet is a copper hollow-point with the tip of the bullet consisting of eight trocar-shaped petals which upon impact act similar to a holesaw. RIP bullets act like a FMJ on impact in solid objects and as the bullet passes through soft tissue it expends its energy. The design allows for an ease of entry by reducing the deceleration at the point of impact causing potential energy to be conserved thus delivering a deadly kinetic energy wave.
