Hornady .300 Blackout 190 Grain, Sub-X Subsonic, Rifle Ammunition – Ultra-Quiet Precision with Devastating Terminal Performance

Hornady .300 Blackout 190 Grain Sub-X Subsonic Rifle Ammunition is purpose-built for suppressed shooting, offering optimal performance at subsonic velocities. Featuring the advanced Sub-X (Subsonic eXpanding) bullet, this load delivers reliable expansion, deep penetration, and near-silent operation, making it ideal for hunters and tactical shooters who demand stealth without sacrificing lethality. Engineered to perform reliably even at lower speeds, the Sub-X bullet incorporates Hornady’s patented Flex Tip® to initiate expansion and ensure consistent terminal performance.
