The Apolo Slug Air Gun Pellet differs significantly from conventional pellets due to its shape. It has been designed for the most powerful rifles that are capable of accurately firing at distances of 50, 100 or even 200m. An extremely favorable ballistic coefficient ensures a flat trajectory and excellent weight retention. In order to adapt to different barrel profiles and power levels, the power of the rifle should be at least 25 joules, but for best results Apolo recommends powers of 40 to 60 joules.
