Geco Zero caliber 8x57IS hunting ammunition 139gr

Best performance in precision and momentary effect is provided by the GECO ZERO with the latest development. The projectiles are lead-free and offer many other advantages for hunting. This highly innovative jacketed projectile 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, ensuring deep penetration and a reliable exit wound. This makes the GECO ZERO an excellent choice with the best suitability for light to medium game.
