Hornady SUB-X 30 Caliber .308 190 Grain FTX Bullets - Box of 100

Hornady SUB-X 30 caliber .308 190 grain FTX bullets are purpose-built for subsonic rifle loads, delivering controlled expansion at velocities as low as 900 fps. If you're reloading for a suppressed rifle or developing subsonic ammunition for .308 platforms, these bullets solve the real challenge of getting reliable expansion below the speed of sound — a problem conventional bullets simply can't handle. The 190-grain weight is optimized for subsonic ballistics in full-power cartridges, making these a smart choice for hunters and shooters who want hearing-safe performance without sacrificing terminal performance.

The design combines proven Hornady engineering with features built for serious reloaders. Each bullet features a patented Flex Tip insert in the hollowpoint cavity, working together with the long grooves in the gilding metal jacket to ensure the bullet opens predictably even at subsonic speeds. A cannelure around the jacket provides a crimp groove for secure case seating in semiautomatic weapons and bolt-action rifles alike, eliminating the guesswork and giving you consistent round-to-round performance. This is ammunition engineering that respects both the rifle and the shooter's intent.

Whether you're a precision rifle reloader, a suppressed-gun enthusiast, or a hunter pursuing quiet, ethical takes, a box of 100 SUB-X bullets gives you the component count to develop reliable loads. These bullets meet FBI protocol for terminal ballistic testing, so you're working with projectiles proven to perform in the real world, not just on paper.

Frequently Asked Questions

Will these bullets work in my suppressed .308 rifle?

Yes. SUB-X bullets are specifically designed for subsonic applications and will expand reliably at the reduced velocities typical of suppressed .308 loads. The Flex Tip technology ensures expansion even below 1,000 fps.

Can I use these in a semiautomatic rifle?

Yes. The cannelured jacket provides a positive crimp groove, making these bullets suitable for semiautomatic weapons as well as bolt-action rifles.

What velocities do these bullets need to expand?

SUB-X bullets are designed to expand at velocities as low as 900 fps, making them ideal for subsonic ammunition development where conventional bullets would fail to open.

Are these bullets loaded ammunition or components only?

These are bullets only — reloading components sold as components for hand loaders to assemble into ammunition. They are not loaded rounds.
