When wild places put you in a tight spot, keep your cool, rely on your skill and call on the unstoppable performance of Solid Core ammunition, from Federal Premium®. Its flat-nose bullet is formed from extremely hard, high-antimony lead to hold together while blowing through bone and penetrating deep, making it an ideal choice for both hunting and dangerous animal defense. Unlike hard-cast bullets, Solid Core uses a Syntech® polymer jacket to reduce friction and leading without features like wax rings and gas checks.
