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

Hornady Sub-X Subsonic eXpanding .45 caliber handgun bullets deliver consistent expansion at velocities below the speed of sound, making them the specialized choice for suppressed .45 ACP platforms and low-velocity handgun applications. These 410-grain projectiles are engineered to expand reliably when fired through sound-suppressed firearms where conventional hollow-point designs often fail to perform due to reduced impact velocity.

The Sub-X design centers on a patented Flex Tip insert positioned within the hollow-point cavity, which works in tandem with long grooves running along the gilding metal jacket to initiate and control expansion at subsonic speeds. The flat-nose profile reduces velocity loss in the suppressor and enhances consistency from barrel to barrel. Dual cannelures ensure positive case crimp during reloading, making these bullets compatible with semiautomatic feeding and reliable in precision reload operations. At 410 grains, the weight class maximizes momentum retention through sound suppressors while maintaining the ballistic stability required for accurate shot placement.

This ammunition is purpose-built for tactical shooters, law enforcement trainers, and precision handgunners who run suppressed .45 ACP setups for duty or defensive applications. Subsonic .45 ammunition eliminates the need for hearing protection on indoor ranges and training scenarios, while maintaining the terminal performance standard-velocity loads are expected to deliver. Reloaders who prioritize accuracy and suppressed-gun performance will find the consistent geometry and cannelured design enable repeatable velocity and point-of-aim precision.
