Engineered from the ground up to enhance range and accuracy, these Hybrid Slugs from FX combine the most desirable attributes of both standard diabolo-shaped pellets and swaged slugs. According to FX, this results in lighter weight, a higher ballistic coefficient and the ability to be shot out of most PCPs with “massive expansion.” “The FX Hybrid Slug will revolutionize what an airgun can do,” writes the manufacturer. “The hybrid benefits from the external dimensions of a high ballistic coefficient slug, but has a completely hollow core and deep recessed base, making it light enough to be shot from most PCPs. Its unique shape and extreme low weight, combined with an optimal bearing surface, all for velocities and trajectories that are unparalleled by any other slug or pellet.” FX Hybrid Slugs have been designed with all PCPs in mind, but are specifically engineered in .25 caliber to deliver best performance in the FX Smooth Twist X (STX) Superior Liner.
