300 AAC BlackOut Subsonic, 220gr Sierra MatchKing - 20 round box


Gorilla Ammunition 300 AAC BlackOut Subsonic features great accuracy and knockdown power from the 220gr Sierra MatchKing Bullet and is much quieter than your standard supersonic ammo. The video below demonstrates just how quiet it can be.

Please note: The reduced pressures associated with subsonic ammunition can affect the proper cycling of gas operated firearms. Subsonic ammunition is best used with a suppressor. Suppressors create more back pressure and help achieve full cycling of the gas operated system.

300 AAC BlackOut is growing in popularity due to it's increased range capabilities over 223 REM / 5.56 NATO. Increased maximum effective range with Super Sonic ammunition and incredible sound signature reductions with SubSonic ammunition make 300 BlackOut an awesome alternative to the 223 REM cartridge.


Gorilla Ammunition utilizes only the highest quality components to manufacture top quality match grade loads and this offering chambered in 300 AAC BlackOut with the 220gr Sierra MatchKing is no exception Factory new cases, match grade primers and top quality projectiles make this load a go to choice for competition or home defense.


Component selection is only the start to our top quality ammunition, the Gorilla Ammunition manufacturing process ensures consistency by pairing proprietary high end linear loading equipment with state-of-the-art inspection equipment. This inspection equipment utilizes lasers and high speed photography equipment to ensure only ammunition that meets our rigorous specifications makes it into the box.


Sierra MatchKing bullets have set an incredible number of new national records. This projectile is well known for it's excellent accuracy. Even with it's pinpoint accuracy we don't recommend hunting with MatchKing bullets.

I have tried every brand of subsonic ammunition that I could find. This brand is very accurate vs the others. I like to hit what I am aiming at.

Shoot Supressed
This is some fun stuff to shoot. I hadn't heard of subsonic ammo until this year when I bought my first can and started reading all the forums about it. I got a blackout gun for my birthday from my wife and decided to get a suppressor for it to shoot this subsonic stuff. I've never had so much fun shooting and neither has my wife. We can shoot it all day long and not get tired from the noise, kick, etc. I'm happy with Gorilla.

Most accurate on the market
I have shot every 220 grain subsonic load I can find with my AAC SBR. This ammo consistently groups under one inch at 100 yards. Great accuracy out of subsonic ammunition finally.

Perfect Ammo
9" Blackout AR, H2 Buffer, Wolff XP Spring, Magpul Magazine. No FTF, no FTE, flawless ammo, and it cycled the action without a suppressor. Can't wait for my can!!

300BLK
I was having trouble with my cmmg 300 blackout, I sent the rifle back to cmmg and the only thing they could say to me was use your ammo, I first started off purchasing 4 boxes of super sonic and had NO issues, so then I ordered 4 boxes of sub sonic ammo, once again NO issues! Thank you for making such consistent rounds.

220gr MatchKing
Hi, I've tried your Troop ammo in my .300 Blackout Handi Rifle. The 208 grain Hornady A-Max was very accurate, but the 220 grain Sierra Match King was even better. I'm not a great marksman, but I put several of the 220 grain SMK's through the same hole at 25 yards with a suppressor attached to the gun. Good stuff!
