Hornady Sub-X (Subsonic eXpanding) bullets are engineered to expand reliably at subsonic velocities while maintaining deep penetration. The design pairs a lead core with a grooved gilding metal jacket and a polymer Flex Tip to promote controlled expansion below the speed of sound. Cannelures provide positive case crimping, making these bullets suitable for many semiautomatic firearm loadings.
