Hornady Sub-X (Subsonic - eXpanding) Rifle Bullets .45 cal .458 410gr Sub-X

Sub-XA(R) (Subsonic - eXpanding) bullets deliver big results without a big bang! Designed to provide deep penetration below the speed of sound, Sub-XA(R) features a lead core. Long grooves in its gilding metal jacket combine with its flat profile and the patented Flex TipA(R) insert within the bullet's hollowpoint cavity to help it expand reliably at low velocities. Cannelures provide positive case crimp, making Sub-XA(R) ideal for semiautomatic weapons.
