Barnes Buster handgun and lever rifle bullets are intended for hunting bear, wild boar, moose, bison, buffalo and other large, even dangerous, game. These tough bullets are specifically designed to deliver maximum penetration, even in large game. It features a thick copper jacket and a heavy lead core, resulting in minimal expansion, deep penetration and maximum weight retention to combine bone-crushing power with pass-through penetration. These cannelured, heavy-for-caliber bullets drive deep through dense muscle and bone. The bullets remain intact; jackets won't separate from the core. Unlike conventional expanding bullets, Barnes Busters track straight without deflection or deformation. The Barnes Buster is 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.
