The LETHAL pellet can acquire up to 38% better grouping than a standard lead pellet*, thanks to the stable trajectory and its longer polymer skirt. The dome tip and the two body design enable this pellet to penetrate a metal plate up to 0.06 in (0.15 cm) thickness. Copper retains 100% of its weight after expansion, retaining velocity/energy - creating less ballistic drag. The shape and long skirt create a flatter trajectory and tighter group patterns. Terminal impact for a clean, vital shot kill. 5.56 grain
