Due to component shortages, we are currently using mil-spec primers in 300BLK loads. These primers contain a harder primer cap designed for use in semi-automatic weapons. You may experience lite strikes in bolt action platforms due to the harder primer cap. Please be aware of this issue before purchasing. For safety reasons, we do not allow returns once the product has been delivered.

    Phenomenal ammo from a phenomenal company keeping the 300 Blackout ammo rolling out during the ammo shortage. Ammo runs supper smooth and quiet through my MCX Rattler Canebrake suppressed. This ammo outperforms any other 300 Blackout ammo I have ran. Keep up the high quality work!

  15. Philip Sanfilippo (verified owner)

    Just the best. Period.

  16. Chris (verified owner)

    I just like that they email you when stock is available and it gets to you pretty quickly. Overall I am pleased with the service and response. I did try to set up an account and fat fingered the password set up, and I’ve never been able to get it fixed. But still, it doesn’t get in the way of ordering.

  17. Ty Prause (verified owner)

    I have become a big fan of Gorilla Ammo—VERY consistent loading and definitely attention to quality and detail!

  18. Noah Burtner (verified owner)

    Shoots smooth and quiet. Very accurate. Couldn’t ask for more consistency. Shipping was fast and box was wrapped well.

  19. pauzny2003 (verified owner)

    Haven’t received my ammo yet. But that is more of an issue with how horrible UPS is as a company! My package was shipped out immediately but unfortunately I kept missing UPS and instead of sending to a local facility UPS they kept sending it back and with the current situation didn’t want to miss out getting this ammo. Gorilla was very helpful with getting my ammo reshipped and should receiving it soon. Their customer service is outstanding and products to match.

  20. Clint C

    Excellent customer service. Quick shipping. The ammo cycles great in my fully suppressed blackout and grips consistently! I will be glad when it is back in stock.

  21. Brandon (verified owner)

    Very satisfied with this ammo! Packaged and sealed in an awesome bucket. Shooting suppressed this ammo is very quiet and cycles perfectly. Also has very tight groups at 100yds. Probably the best grouping ammo for 300blk I have found. Looking forward to trying out the 205gr Silverback ammo.

  22. Snake Eyes (verified owner)

    Shipped super fast. Great company and ammo. This was my third time ordering from them and it has been a great experience every time. This ammo consistently shoots around a 1/2″ group at 50yd out of my psa 7.5″ barrels. The (3) gorilla blk out loads I’ve tried(125g,150g & 220g) have all feed flawlessly in my gen3 pmags and 300blk out pmags.

  23. Michael (verified owner)

    I like the ammo, but would very much appreciate a 205 grain self defense round in the future

Gorilla 300 AAC BlackOut Subsonic, 220gr Sierra MatchKing – 160 Round Bucket

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.
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. Component selection is only the start to our top quality ammunition, the Gorilla Ammunition manufacturing process ensures consistency by pairing high end linear loading equipment with multi stage in-process inspections by highly trained machine operators with a final inspection of each and every round by our quality inspectors 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. 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.
