Hornady® has made a revolutionary breakthrough — without breaking the sound barrier. Hornady® Subsonic Ammunition for 300 Blackout represents the rst truly and reliably expanding subsonic round. Other subsonic rounds may expand, but petals shear off, causing the bullet to veer off course.
Here’s how Hornady® engineers solved that problem. The hollow-point cavity of the Sub-X (Subsonic — eXpanding) bullet features the patented Flex Tip® insert, which helps the bullet expand at low velocities.
That results in deep penetration and large wound channels with no loss of accuracy, proving that you don’t have to be fast and loud to make a big impact.
