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.

    Have not used the ammo yet but order delivered timely, as expected. Thank you

    This ammo is great for hunting wild boar. It is super accurate, dependable, and very quiet when used with a silencer. The bullet expansion is amazing, routinely opening up to a four-point star with near 1000% weight retention, as depicted in the photograph.

  3. Billie Harris

    This ammo is lethal without a dobut. 56yd broadside shot on a 150lb boar. It actually ran toward me and dropped at about 20yds. Clean pass through, lots of blood loss and a quick ethical kill. Now for the negative. I purchased this ammo last year and didn’t see the fine print about “Hard primers”. This ammo goes off 50/50 in my boltaction and single shot, but is 100% reliable in my AR. I hope the primer issue is resolved and this will be 5 star ammo all day.
