Hornady Subsonic 350 Legend 250 Grain SUB-X FTX Ammunition - 20 Rounds

The Hornady Subsonic 350 Legend 250 Grain SUB-X FTX Ammunition is purpose-built for shooters who want effective medium-game performance without the blast. Loaded with a 250-grain Sub-X bullet featuring Hornady's Flex Tip polymer insert, this subsonic rifle ammo delivers reliable expansion at velocities below the sound barrier—a serious advantage when hunting with a suppressor or in situations where noise discipline matters.

What sets subsonic ammunition apart is the deliberate engineering that happens below the speed of sound. Hornady's 350 Legend subsonic load uses specially selected powders that maintain consistency and minimize flash signature, whether you're running suppressed or unsuppressed. The Sub-X bullet combines a lead core, gilding metal jacket with long grooves, and that signature Flex Tip hollow-point cavity to ensure reliable expansion even at the lower velocities inherent to subsonic loads. This matters: at subsonic speeds, traditional bullets may fail to open up, and the Sub-X is specifically designed to overcome that challenge.

Each box contains 20 rounds of Hornady's quality control—high-quality cartridge cases and primers that keep performance consistent from shot to shot. The 350 Legend platform itself is a modern, efficient straight-wall cartridge that's become a favorite for hunters working within suppressed or noise-conscious shooting, especially in medium-game applications. If you're running a suppressed 350 Legend rifle or simply want serious ballistic performance without the report, subsonic ammunition in this loading is the smart choice.

Frequently Asked Questions

Will Hornady Subsonic 350 Legend ammunition work with a suppressor?

Yes—subsonic ammunition is designed to perform at velocities below the speed of sound. When paired with a suppressor, this load provides a significantly quieter shooting experience compared to standard supersonic rounds, and the powder selection helps minimize flash signature as well.

Is the Sub-X bullet reliable for hunting medium-sized game?

The Sub-X is specifically engineered for expansion at subsonic velocities, which is critical since traditional bullets may not open reliably at lower speeds. The Flex Tip insert and hollow-point design work together to ensure controlled expansion on game in the 50–300-pound range.

What's included in a box of Hornady Subsonic 350 Legend ammunition?

Each box contains 20 rounds of loaded ammunition, complete with Hornady's high-quality cartridge cases and primers.

Can I shoot this ammunition unsuppressed?

Yes. While subsonic ammunition delivers its greatest advantages when paired with a suppressor, it functions in unsuppressed rifles as well. The optimized powders and low flash signature make it suitable for either configuration.
