Hornady Subsonic Ammunition 450 Bushmaster 395 Grain SUB-X FTX 20RD

Hornady Subsonic Ammunition in 450 Bushmaster with 395 grain Sub-X FTX bullets is purpose-built for shooters who want effective medium-game performance without the crack of a supersonic round. Whether you're hunting with a suppressor or shooting unsuppressed, this ammunition delivers the low-velocity reliability that makes subsonic loads practical for hunting situations where noise matters—from suppressed setups to areas with noise concerns. The 450 Bushmaster cartridge itself is known for hard-hitting performance in short-range hunting scenarios, and Hornady's subsonic loading keeps that energy in the subsonic window.

The Sub-X bullet design is where Hornady's subsonic expertise shows. Its lead core, gilding metal jacket with long grooves, and flat profile work together with a patented Flex Tip insert inside the hollowpoint cavity to achieve reliable expansion even at the lower velocities that define subsonic loads. This matters: low-velocity expansion is harder to achieve than supersonic performance, and Hornady engineered this round specifically for that challenge. The result is a bullet that opens up predictably on medium-sized game in the 50–300 pound range.

Hornady selected powders optimized specifically for subsonic velocities to ensure consistency and a low flash signature—useful whether you're running a suppressor or shooting in low-light conditions. The ammunition uses quality cartridge cases and primers throughout, so you get the accuracy and performance standards Hornady is known for, lot after lot. Each box contains 20 rounds.

Frequently Asked Questions

What is subsonic ammunition, and why would I use it?

Subsonic ammunition is loaded to produce muzzle velocities below the speed of sound (roughly 1,125 fps), so the bullet doesn't create a supersonic crack. When paired with a suppressor, subsonic rounds are significantly quieter than standard loads, making them valuable for hunting situations where noise control matters. They also produce a lower flash signature, which can be useful in low-light conditions.

Will this 450 Bushmaster subsonic round expand reliably on game?

Yes. The Sub-X FTX bullet is specifically engineered for expansion at subsonic velocities. Its Flex Tip insert, flat profile, and long-groove jacket work together to achieve consistent expansion on medium game in the 50–300 pound range, even though the bullet is traveling slower than a standard supersonic load.

What's included in a box?

Each box contains 20 rounds of loaded ammunition ready to shoot.

Can I shoot this unsuppressed?

Yes. While subsonic ammunition is often paired with suppressors for maximum noise reduction, it will function in any firearm chambered for 450 Bushmaster. Even without a suppressor, the lower powder charge produces less report than supersonic ammunition and a lower flash signature.
