Gamo USA Red Fire Pellets, .22 Pellets, 125/Pack 632270454 Experience match-grade accuracy" high-velocity performance and hydraulic expansion at point of impact with Gamo's Red Fire. The diamond shaped hard polymer tip provides a true ballistic trajectory. The force of impact drives the diamond polymer tip into the cylindrical jacket material forcing it to expand outward-increasing the diameter of the projectile as it passes through the intended target (mushrooming effect on impact).
