Barnes now offers a new deep penetrating handgun bullet intended for hunting bear, wild boar, moose, bison, buffalo and other large even dangerous game. The bullet features a thick copper jacket and a heavy lead core, resulting in minimal expansion, deep penetration and maximum weight retention.Available for .44, .45, and .500 magnum revolvers, as well as for .45-70 rifles, this premium hunting bullet combines bone crushing power with pass through penetration. Unlike conventional expanding bullets, the Barnes Busters track straight without deflection or deformation. These tough bullets are specifically designed to deliver maximum penetration, even in large game. In one field test, a Barnes Buster fired from a .45-70 T/C Encore drove completely through an American bison, anchoring it on the spot. These cannelured, heavy for caliber bullets drive deep through dense muscle and bone. Bullets remain intact jackets won't separate from the core. Great for hunting hogs and tough, heavy game. It's the ideal bullet for those who carry handguns for protection against bears in Alaska and other wilderness areas.
