.357 | 250gr | Hornady Sub-X
by Hornady
The Hornady Sub-X bullet is engineered for subsonic velocities, featuring a progressive design that includes a polymer Flex Tip insert within a long cavity. This allows for reliable expansion at lower speeds, a critical factor when working with subsonic loads. Its construction utilizes a lead core encapsulated by a precision-drawn jacket, ensuring consistent weight retention and enhanced penetration. Expansion is moderate and controlled, maximizing terminal performance while maintaining deep penetration, suitable for medium-sized game. With typical calibers being 300 Blackout and similar, this bullet is optimized for hunters targeting deer and hogs at closer ranges where subsonic ammunition is preferable. The Sub-X's design reduces the sonic crack while still delivering terminal effectiveness, ideal for suppressor use. For handloaders, the bullet's uniform build and the performance-driven design simplify load development, ensuring repeatable results across various load recipes, making it a versatile choice for custom load applications.
