These H&N Slug HP II Air Gun Pellets are made in a variety of weights, so that you can get additional range without giving up power or precision. They keep more of their energy until impact and have a high ballistic coefficient and higher speeds because of their hollow point design, which also has superior expansion at the target. You'll get a slug with high dependability because of the tighter weight and size tolerances of their swaged design. Shoot farther and with better accuracy than you previously imagined.
