Take aim with this 150ct tin of .117 7.8-grain Gamo Red Fire Pellets. The Red Fire is Gamo’s latest state-of-the-art hunting pellet. This advanced pellet is designed with a diamond shaped polymer tip that provides a true ballistic trajectory. The Red Fire is engineered for balanced expansion ensuring intense penetration. The force of impact drives the red polymer tip back into the cylindrical jacket material forcing it to expand outwards increasing the diameter of the projectile as it passes through the intended target (mushrooming effect on impact).
