"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 .06"" 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.
