Gorilla 300 AAC BlackOut Subsonic 220gr Sierra MatchKing – 160 Round Bucket
*Adult Signature Required*
Due to component shortages, we are currently using mil-spec primers in some of our 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. If you would like to check availability of 300BLK ammo for use in your bolt action platform, please contact us before purchasing.

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.

Best 300 blk I have used

I love Gorilla Ammunition! Even out of a DDM4 PDW w/ a 7″ barrel at 50 yards I get ridiculously small groups. All other ammo I’ve used does not come close.
Your 5 star rating should go to 6.
