Hornady Sub-X® .311 255 gr (3148)

The Hornady Sub-X® (Subsonic eXpanding) bullet is designed to deliver reliable expansion at subsonic velocities. A Flex Tip® insert helps initiate expansion even at low speed, while the InterLock® ring keeps the jacket and lead core together for deep penetration and high retained weight. A cannelured jacket provides a positive case crimp for use in semi-automatic firearms.
