Slower than the speed of sound! This 300 AAC Blackout cartridge by Remington is loaded with a big, heavy bullet to tamp its muzzle velocity all the way down to a mere 940 fps. Its going to demonstrate a steeper trajectory than a supersonic load – but it’s also going to be a whole heckuva lot quieter. That’s optimal if your AR has a suppressor, but you’re going to notice this ammo’s subtlety even if you haven’t got a suppressor device attached to the end of your barrel.

While it may not be very fast, this round’s bullet is plenty accurate. The OTFB features a form-fitted lead core for superior rotational stability, and its flat base creates the most uniform possible surface for propellant gasses to push up against during ignition. Do take note that this bullet isn’t engineered to expand in soft tissue – the opening in its tip is there because the lead core was poured through it during the bullet’s creation.

This loose-packed ammo has Remington’s standard brass cases, which are by all means reliable and reloadable, as well as non-corrosive primers and clean-burning propellant. Great for target shooting, nighttime varmint hunts and home defense when you don’t want to drive yourself deaf!

A: Thanks for reaching out! I'm afraid 300 AAC Blackout is not compatible with a 300 Win Mag rifle. We haven't gor any 220gr 300 Win Mag in ammo in stock for you right now (although we do update our inventory constantly). Best we can do for you at the moment is 150gr Core-Lokt:
