Hrndy 450bm 395gr Sub-x 20/200

The Hornady 450 Bushmaster 395gr Sub-X subsonic ammunition is purpose-built for suppressed rifle applications where velocity must stay below the sound barrier. Subsonic loads eliminate supersonic crack while maintaining reliable expansion through the Sub-X bullet's flat profile, grooved gilding metal jacket, and patented Flex Tip® insert design. This ammunition cycles consistently in semiautomatic and bolt-action platforms chambered in 450 Bushmaster, delivering energy management suited to short-range precision work.

At approximately 1050 feet per second, the 395-grain bullet maintains subsonic performance across a wide range of barrel lengths and suppressor configurations. The heavy bullet weight, combined with optimized powders selected for lot-to-lot consistency, ensures predictable ballistics that do not vary between production runs—critical for shooters stacking shots at distance or relying on ammunition in duty applications. The lead core construction and Flex Tip® design work together to achieve reliable expansion at reduced velocities where traditional hollow points may not perform adequately.

This load is engineered for shooters running suppressed 450 Bushmaster rifles in law enforcement, military training, hunting, and precision rifle disciplines. The 450 Bushmaster platform is favored for its deep subsonic performance envelope and barrier-blind terminal ballistics. The Sub-X ammunition eliminates the complexity of load development by delivering factory-matched subsonic ammunition that performs with or without a suppressor attached, making it ideal for shooters who require hearing-safe operation without audible crack downrange or precision-critical performance at modest ranges.

Each box contains 20 rounds of factory-loaded ammunition. The 450 Bushmaster cartridge offers a large propellant capacity and heavy-bullet platform that excels in subsonic applications, standing apart from the velocity-dependent performance of lighter cartridges in reduced-speed loads. Serious operators and precision shooters running suppressed rifle systems understand that subsonic ammunition must be engineered specifically for low-velocity performance—standard ammunition simply will not expand reliably at subsonic speeds. Hornady's engineering addresses this gap directly.
