Hornady Sub-X .452 Caliber 395 Grain Subsonic Expanding Bullets, Part 45031, 50 Count

Hornady Sub-X Subsonic eXpanding bullets are designed for reliable expansion and deep penetration at subsonic velocities. Part 45031 features a heavy 395-grain lead core, a brass gilding metal jacket, and a patented Flex Tip insert positioned within the hollow point cavity. This combination helps the bullet expand reliably even when driven at lower speeds, making it well suited for subsonic reloading applications where controlled performance is important.
The Sub-X design incorporates long grooves in the jacket and a flat-profile nose to support consistent bullet function at subsonic velocities. The polymer Flex Tip helps initiate expansion while maintaining the streamlined construction of the bullet. A cannelure provides a positive case crimp, helping secure the bullet during feeding and cycling in compatible semiautomatic firearms. With a .300 ballistic coefficient and .276 sectional density, this bullet is engineered for dependable flight characteristics within its intended subsonic load parameters.
Each box contains 50 Hornady Sub-X .452 caliber reloading bullets. The lead core and polymer tip are paired with a brass jacket for a balanced construction that supports expansion and penetration. These component bullets are intended for experienced reloaders who follow published load data and use appropriate equipment for their firearm and cartridge. As with all reloading components, verify caliber, seating depth, powder charge, and overall load compatibility before use. Hornady’s Sub-X design provides a specialized option for shooters seeking expanding performance from subsonic ammunition.
