The Barnes .458 Cal 450 gr TSX bullet (Barnes part no. 30619) is machined from 100 percent copper rather than a lead core and gilding jacket, so it never loses mass to jacket separation the way a conventional bullet can. On impact the nose petals peel back into four razor-sharp cutting blades that punch a wide, deep wound channel through dense bone and muscle, while the shank retains essentially all of its original weight for a straight, deep path to the vitals on the heaviest game. Barnes recommends seating this bullet between 0.03 and 0.07 inch off the lands, adjusted to the individual rifle, for best accuracy.
