Geco Zero caliber 8x57IRS hunting ammunition 139gr

GECO ZERO is the latest development from GECO in caliber 8x57IRS. It is characterized by excellent precision and outstanding momentary effect - and all of this without lead! This highly innovative jacketed bullet features two tin cores. Supported by the hollow point construction, the pre-fragmented front core disintegrates immediately upon impact with the game body and releases a large portion of the energy, quickly immobilizing the animal. The rear tin core forms a stable residual body with the jacket and ensures deep penetration and a reliable exit wound. This makes the GECO ZERO an excellent choice with the best suitability for light to medium game.
