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.

    First off this ammo is awesome! It feeds and functions flawlessly, out of a DD pdw. I was very impressed with the accuracy as well. If your looking for quality ammo at a good price this is it!

    Good price and I really like the compactness & moisture resistance of the bulk packaging.

  4. J.House (verified owner)

    Best ammo I’ve ever shot. Clean, consistent, and never any cycle issues. Best part about these guys, they aren’t price gouging with the rest of the ammo crooks. Top end ammo for reman prices.
    I have email notifications turned on for every caliber I use on their website.
