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.

    Very happy with these. Consistently stacked rounds on top of one another out of my 9” AR pistol @ 50 yards.

    Have not tested the items purchased. However, I did place 2 different orders at different times, they shipped same day order placed and received in 3-4 days. Great service getting orders processed and out the door.

    Best ammo out of all the brands I’ve tried during the great ammo shortage of 2016-2020s. I’ve had jams, hangs, popcorns, and other horrible things happens with other brands, even well known brands that were more expensive. Gorilla was the best.
