Hornady Sub-X .308 Caliber 175 Grain Subsonic Expanding Reloading Bullets, Part 30718, 100 Count

Hornady Sub-X reloading bullets are designed for subsonic rifle loads that prioritize dependable expansion and deep penetration at reduced velocities. Part 30718 features a 175-grain Subsonic eXpanding bullet with a lead core, brass jacket, and polymer Flex Tip insert positioned inside the hollow point cavity. This construction helps initiate controlled expansion when the bullet is traveling below the speed of sound, making Sub-X a practical choice for compatible handloading applications.
The bullet’s flat profile and long jacket grooves are engineered to support reliable performance across the intended subsonic velocity range. The patented Flex Tip insert helps resist cavity blockage while promoting expansion on impact, and the lead core provides the mass needed for consistent penetration. With a .300 ballistic coefficient and .264 sectional density, this bullet offers a balanced design for reloaders seeking subsonic performance from compatible .308-caliber rifles.
A built-in cannelure supports a positive case crimp, helping secure the bullet during feeding and handling. The 100-count box provides components for developing and assembling multiple handloads according to established reloading practices. Hornady Sub-X bullets are intended for use as reloading components only and should be matched with appropriate brass, primers, powders, seating depths, and published load data. Always follow current manufacturer and load manual guidance, and verify firearm and ammunition compatibility before use.
