Geco Zero Cartridges - Cal. 8x57 JRS 8x57 JRS / Per 1

GECO ZERO is the latest cartridge developed by GECO. It stands out for its exceptional accuracy and excellent impact performance—and it does so without using lead! With a radical innovation, GECO designed a jacketed bullet made up of two tin cores. Thanks to its hollow point, the pre-fragmented front core deforms immediately on impact, releasing much of its energy for an instant impact effect. The second tin core behind it, together with its jacket, forms the stable residual section, ensuring deep penetration and exit from the target. Thanks to these features, GECO ZERO ammunition is an excellent choice, perfectly suited to medium-to-heavy game.
