Nitro Pheasant uses Copper-Lokt copper plated lead shot with high antimony content, the hardest lead made for hunting. Hard shot stays rounder for truer flight, tighter patterns, and greater penetration. Available in both high velocity and magnum loadings in either 12 or 20 gauge, Nitro Pheasant loads will give you the maximum pattern density and lethal energy needed to bring down those tough birds.
