What Is Subsonic 300 Blackout Ammo and Why Use It?

Subsonic 300 Blackout ammo is engineered to travel below the speed of sound (approximately 1,100 feet per second), making it significantly quieter than supersonic alternatives, especially when paired with a suppressor. Subsonic 300 BLK rounds are typically heavier, with common options like 220 grain 300 Blackout loads providing excellent energy transfer at close range with reduced recoil and noise.

Designed with stealth and comfort in mind, subsonic 300 BLK is a top choice for suppressed shooting, home defense, and hog hunting in close-quarters environments. The heavier bullets retain momentum well, and while they sacrifice some long-range performance, their quiet operation makes them ideal for tactical use or backyard shooting where sound control matters.

If you're deciding between subsonic and supersonic options, or want a breakdown by use case, check out our full guide on the best subsonic 300 Blackout ammo. You can also explore the ballistics of 300 Blackout to compare how different loads perform in terms of velocity, energy, and drop.

Was a little iffy about performance, seeing a couple of negative reviews. Performed fine. No issues, no jams, no problem. Great value. At the range I frequent, with range membership, I get about 50% off and comes out to about $325 per 1,000 rounds. I ordered 2,000 rounds of these and paid just under $500...realizing about $100 saving.

Had a couple issues with feeding but swapped to a heavier buffer/spring and it ran flawlessly
PoolGuy said:
The ammunition runs fine out of an SBR. I purchased this ammo in hopes that it would function in my 10.5 inch CMMG banshee. As one would expect the ammo runs fairly consistent without a suppressor. With a suppressor it’s no different than most other options that you can find for a better price. The ammunition arrived to me in a crush box, but all were intact with no damage. I rate the quality of the ammunition as a four out of 10 stars.

I shot a bunch of Federal, Sig Sauer, but my AR really liked this stuff out at 100 yards. The Sig performed well too. The Federal was all over the place. I was shooting light grains. Good clean quality accurate ammo. The price is great too.

This is my second purchase of this ammo. The first purchase was 60 rounds. I had a great time zeroing and shoot the rifle suppressed. This ammo out performed my expectations. This purchase was 200 rounds for $342.00 including shipping. So $1.60 delivered to the front door was worth it to me. Happy shooting.

Bought this ammo for a Run N Gun competition, it worked falsely as it should. I reload my own but with the short notice of this shoot I did not have the time to reload my own. I have some to trust Hornady products as I use there Lock N Load AP Ammo plant press. This ammo was great and was super quiet with my 10.5" SBR I will be getting some more soon so I have the brass to save this time.

I used these rounds a couple of weeks ago hog hunting. 2 bullets fired, 2 hogs down! 97 lbs and 104lbs. Good head shot placement. They both went down immediately, didn't even take one step.

Bullet Points: 300 Blackout Ammo

Developed in 2010 with the intention of offering a .30 caliber cartridge with improved performance over the currently used 5.56mm, the .300 Blackout is compatible with the M4 weapon system – making it an ideal replacement for military use during the global war on terror.
With the use of a .300 Blackout supersonic load, the max effective range is listed at 500 yards. With subsonic loads, it's listed at 220 yards.
For civilian use, .300 Blackout ammo increases versatility of the AR-15 platform – allowing hunters to easily harvest medium-sized game animals with stellar accuracy and controllable recoil.
