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.

  1. Chris W (verified owner)

    I Love the ammo and it’s very accurate.I got it for close range hunting and home defense.I’ve never had any reliability issues.The best subsonic ammo in my opinion.

  2. Phil Lee (verified owner)

    I give the 300 blk out, 205 gr, subsonic 4 stars. That’s only because I have only shot targets with it. My 10.5 inch pistol with a Surefire socom 300 suppressor, in a shooting vise, will make a 3 round cloverleaf at 100 yards. I have no doubt that the expansion and knock down power will be just as impressive.

  3. David Brown (verified owner)

    The expansion performed exactly as it stated. There were no feeding or jamming issues. I would definitely buy again.

  4. C. Martinez (verified owner)

    Excellent ammo. I purchased 5 boxes a couple months ago to try it out. Liked it so much I bought 5 more during their Black Friday sale! I’ve been a fan of Gorilla ammo for a while and have tried several of their 300 Blk loads. Never been disappointed yet. High quality, reliable stuff!

  5. Jay Caccese (verified owner)

    Incredible round. Almost silent through a suppressor. Great expansion. It’s my hog ammo under 100 meters.

  6. Michael Leisure (verified owner)

    Bought 2 boxes to try out for last hunting season. Dropped an 11 point and 12 point in their tracks at 25 yards out with suppressor. Great ammo in my opinion. Cycles great in my 16″ upper with no feeding concerns.
    I want more ammo now and this is always out of stock. Even signing up for the email alerts, it is sold out within minutes before I can repurchase. May need to venture somewhere else unfortunately.
    Definitely recommend this hunting ammo if you can get any of it.

  7. ricoscucchi (verified owner)

    Amazing ammo. This is the best Subsonic on the market as far as I am concerned.

  8. Austin

    This ammo has performed extremely well for me. I have shot it suppressed with a YHM Resonator and it sounds like a nail gun. I’ve dropped two hogs with head/neck shots and shot another center mass with a full pass through and good blood trail. Found the hog 40 yards away. The hogs will usually come back because they don’t know what happened. I’ve also used the Barnes 110 Tac-X for farther shots and they will also drop hogs with head/neck shots.

  9. DRTYEAGLE (verified owner)

    Whitetail at 35yrds with a SIG Rattler (5.5 inch barrel and suppressor). Perfect shot through the heart and out the other side, lots of internal damage. Deer dropped 15 yards away. Very comfortable with this inside 35 yards for sure!
