The Hornady SUB-X 450 Bushmaster .452" 395 Grain FTX bullets are purpose-built for reloaders pushing heavy, slow-moving rounds through big-bore rifles. If you're working up subsonic loads for your 450 Bushmaster—whether for suppressed hunting, dense-cover stalking, or backyard range sessions where noise matters—these bullets are engineered to perform reliably at velocities where most conventional projectiles simply won't expand. The 395-grain weight sits at the heavier end of the 450 Bushmaster spectrum, delivering momentum and energy even at subsonic speeds.
What makes SUB-X different is the Flex Tip insert in the hollowpoint cavity. Rather than relying on velocity-dependent expansion common to traditional hollow points, Flex Tip technology allows reliable mushrooming at speeds as low as 900 fps—well below supersonic velocity. That matters for subsonic shooters: you get consistent terminal performance without needing to run hot loads. The lead core and long jacket grooves work together to ensure controlled expansion while maintaining structural integrity for deep penetration.
Hornady built these bullets to meet FBI protocol terminal ballistic standards, so they're proven in real-world performance testing, not just marketing claims. The cannelured gilding metal jacket provides a positive crimp groove, making them stable and reliable in semiautomatic firearms where case crimp security is non-negotiable. These are versatile enough to feed and function across a range of 450 Bushmaster platforms—from AR-type uppers to bolt-action big bores.
Reloaders appreciate the consistency Hornady brings to component manufacturing. You're getting 50 bullets per box, ready to load into your favorite 450 Bushmaster brass. Whether you're chasing subsonic ballistics for a suppressed rig, hunting thick cover where a heavier, slower bullet excels, or simply exploring what your 450 can do on the quiet end of the spectrum, SUB-X delivers the specialized performance these unconventional loads demand.
| Caliber | .450 Bushmaster |
| Bullet Diameter | .452" |

| Count per Box | 50 |
| Core Material | Lead |
| Jacket Material | Gilding metal with cannelure |
Yes. The Flex Tip insert is specifically engineered for expansion at velocities as low as 900 fps. This is a key advantage if you're running subsonic 450 Bushmaster loads through a suppressed rifle or in any scenario where low velocity is the design goal.
Yes. The cannelured jacket provides a positive case crimp, which is important for feeding reliability and safety in semiautomatic platforms, including AR-type 450 Bushmaster uppers and other gas-system rifles.
SUB-X bullets are designed to meet FBI protocol for terminal ballistic test requirements, meaning their expansion and penetration characteristics have been validated against a recognized standard for handgun and rifle ammunition performance.
This product description covers only the bullets themselves. Refer to your 450 Bushmaster reloading manual for the correct brass, primer, and powder specifications for your intended load.
