The X-Bullet is a solid copper projectile, heat treated for extra toughness. There's no separate jacket and no lead core. The bullet holds together for deep, dependable penetration---every time! A deep forward cavity causes the nose to peel back in four separate, razor-edged petals. Viewed head on, the appearance of these four petals gives the X-Bullet its name. The X-Bullet out-penetrates other hunting bullets, and has developed a reputation for delivering quick, one-shot kills on a wide variety of game. This is not loaded ammunition.
