Is .300 AAC the Same as .300 Blackout?

Yes, .300 AAC, .300 Blackout, 300 Blk, and .300 AAC Blackout all refer to the same cartridge. The “AAC” comes from Advanced Armament Corporation, the company that invented the round in 2011 alongside Remington Defense.

Is .300 Blackout Ammo Subsonic?

You can find .300 AAC Blackout ammo in both subsonic and supersonic loads. Because the caliber was designed for use in suppressed, short-barreled firearms, its velocity tends to be far lower than that of 5.56 NATO — the round it was made as an alternative to. That velocity range still stretches above the sound barrier, but the lower end sits comfortably below it. Options like Hornady Subsonic .300 Blackout and Barnes Suppressor Series .300 Blackout let you take full advantage of this cartridge’s lower velocity for a quieter shot. If you prefer something with a bigger punch, ammunition like Ammo Inc. Signature Hunting .300 Blackout or Hornady Black .300 Blackout are solid supersonic options.

What Is .300 Blackout Good For?

AAC may have designed the .300 Blackout cartridge for military applications, but it’s an excellent hunting cartridge, too. With a larger, slower-moving bullet than 5.56 NATO, it can be a more effective round at shorter distances. It’s particularly popular among hog hunters, as subsonic ammo lets you hunt at night without causing as much of a disturbance. As you might expect given its military history, .300 AAC Blackout can be a great self-defense cartridge, too. This round was made for use in tight quarters, and the noise factor can also help in these situations.

Is .300 Blackout Good for Deer?

While it may be most popular as a hog round, .300 Blackout can be a great deer cartridge with the right ammo. Keep in mind that you won’t get as much range out of this caliber as you would with 5.56, but it will be effective as long as you’re within 200 yards. Be sure to use expanding rounds, too, as .300 Blackout full-metal jacket ammo may not be legal to hunt with in all states.

Does .300 Blackout Fit in a 5.56 Mag?

Yes, .300 Blackout ammunition will fit in a 5.56 magazine. The two cartridges have identical total length and case diameter. However, that does not mean you can use a mag full of .300 Blackout rounds in a barrel chambered for 5.56 NATO. Even if the overall dimensions look the same, .300 Blackout has a wider, heavier bullet and a shorter case. You can still use the same rifle for both, but you’ll have to swap barrels when switching between them.
