Hornady Subsonic 7.62x39mm 255gr SUB-X Polymer Tip Ammo - 20 Rounds

Hornady Subsonic 7.62x39mm ammunition delivers effective performance below the speed of sound, making it an excellent choice for suppressed shooting or situations where noise signature matters. The SUB-X polymer tip design uses long grooves in the gilding metal jacket combined with a patented Flex Tip insert to achieve reliable expansion even at subsonic velocities. Each round carries a 255-grain bullet and ships in convenient 20-round boxes, ideal for testing loads or stocking subsonic-specific practice and hunting ammunition.

The subsonic platform is engineered around controlled velocity and consistency. Hornady selects powders specifically for optimal subsonic performance and lot-to-lot uniformity, which translates to more predictable ballistics and tighter shot grouping at the distances where you'll typically shoot subsonic loads. Whether you're running a suppressor or shooting unsuppressed, the low flash signature and controlled report make this round suitable for both tactical applications and hunting scenarios where stealth is a priority.

Built on quality components—durable cartridge cases and reliable primers—this ammunition maintains the accuracy standards Hornady shooters depend on. The 7.62x39mm cartridge itself is well-suited to suppressed platforms and modern plinkers, and subsonic loads eliminate the supersonic crack, leaving only the mechanical sound of the action and suppressor. If you're running a can on a 7.62x39mm rifle and want ammunition engineered specifically for that setup, Hornady Subsonic delivers the ballistic performance and consistency to make it worth your investment.

Specifications

Frequently Asked Questions

Is this ammunition designed for suppressed rifles?

Yes. Hornady Subsonic ammunition is engineered specifically for subsonic performance—velocities below the sound barrier. Paired with a suppressor, it produces minimal noise. The low flash signature also makes it effective unsuppressed if you prefer to minimize muzzle flash and report.

What makes the SUB-X bullet expand reliably at subsonic speeds?

The SUB-X design combines long grooves in the gilding metal jacket with a patented Flex Tip polymer insert in the hollowpoint cavity. This combination promotes reliable expansion even at the lower velocities characteristic of subsonic loads, where traditional hollow-points may not open consistently.

What's the bullet weight?

The SUB-X bullet is 255 grains, which provides the mass and sectional density needed for effective performance on medium game and varmint-sized targets at subsonic velocities.

How many rounds are in a box?

Each box contains 20 rounds of 7.62x39mm Subsonic ammunition.
