Ammo Inc. Stelth 300 Blackout Ammo Subsonic 220 Grain FMJ

Subsonic 300 Blackout

AMMO Inc. built Stelth for shooters running a suppressor on a .300 AAC Blackout rifle or pistol. Each round pushes a heavy 220-grain bullet at a subsonic 1,071 fps, which is below the speed of sound, so the bullet does not make the sharp supersonic crack that a suppressor cannot stop. The box is printed "Specifically designed for use with suppressors," and the load is made to keep your can cleaner and your shooting quieter.

Features

• .300 AAC Blackout Caliber — Chambered for 300 Blackout firearms, a .30-caliber cartridge that runs in AR-15 platforms with a barrel change.
• 220 Grain Bullet — The heavy bullet keeps energy up at subsonic speed and helps cycle suppressed actions.
• Total Metal Coating — The box lists the bullet as TMC, meaning the lead core is fully encased in metal, base included, so less exposed lead burns off when you fire it.
• Subsonic 1,071 FPS — Muzzle velocity stays under the speed of sound, so a suppressor can do its job without a sonic crack downrange.
• 560 Ft-Lbs Muzzle Energy — The load produces 560 foot-pounds at the muzzle, a useful figure for comparing it with other subsonic loads.
• Hyperclean Technology — AMMO Inc.'s Hyperclean design is made to reduce lead emissions and slow baffle erosion, the wear on the internal walls of a suppressor that trap and cool gas.
• Brass Cases — The cases are brass and Boxer primed, which means a single central flash hole and makes them practical to reload.
• Non-Corrosive Primers — The primers leave no corrosive salts behind, so the bore does not need special cleaning after a session.
• 20 Rounds Per Box — Each box holds 20 cartridges and has a thumb cutout that makes the tray easy to slide open.

Built For Suppressors

Suppressed shooting puts more fouling and heat through a can than people expect. Stelth addresses both with a fully coated bullet and a load that keeps lead and baffle wear down. The rounds are commercial manufacture from AMMO Inc., loaded in new brass with Boxer primers. Check that your firearm is chambered for .300 AAC Blackout before loading, and never fire it in a 5.56 or .223 chamber.
