Gamo Red Fire Energy Pellets. Built around a diamond-shaped, hard polymer tip, this advanced pellet provides a true ballistic trajectory and an effective and balanced mushrooming effect after impact. Designed to ensure intense penetration and effective expansion, the Red Fire’s tip pushes back into the pellet’s cylindrical jacket upon impact. As the tip moves back into the jacket, it forces the jacket material outward for an effective and balanced mushrooming effect through the intended target. Exceptional, match grade accuracy with intense penetration and uniform hydraulic expansion. Please note that these pellets are 10mm long so may not fit in all magazines.
