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.

    Super accurate and cycles great suppressed.

  2. David Kitchen Sr. (verified owner)

    205 gr Silverback is in a league all its own. I have a 9” barrel Sig Sauer MCX and 7” barrel Daniel Defense DDM4 (both are suppressed). I’m tempted to use the phrase “Hollywood Quiet,” but whatever term/phrase you use, these rounds are engineered to have unsurpassed terminal performance/terminal ballistics and to match perfectly with a suppressor. And they’re the most accurate subsonic load I’ve ever used. Full throttle performance is out to 100 – 125 yards; within that range, if you make a semi-decent shot, the animal being targeted drops immediately. For personal defense, nothing competes; in that it will drop a deer or large boar, it should go without saying that it will drop any “bad” guy who is threatening you or loved ones. These rounds are devastating! I keep both my 300 BLK AR Pistols loaded with these rounds and I never worry about stopping power. Quiet and deadly!

    Great service…Gorilla contacted me as soon as the ammo was back in stock.

  4. Daniel Sileck (verified owner)

    I found this round to be very pleasant to fire with great accuracy. I would highly recommend this round if looking for a sub in 300 blackout.

    I was looking for a good self defense round for my HD/CQB 300 BLK pistol. After watching some videos, I found the Silverbacks on James Yeager’s and Mrgunsngear’s reviews. As soon as Gorilla sent me the in stock notification, I grabbed some. I ran some at the range, to make sure they fed and cycled fine, which they did. Hopefully I’ll never need them for HD, but if I do, I know that I have rounds in my mags that will end the situation in my favor.

    I am beyond happy with gorilla ammo. They are my goto round now. I am always on their wait list. I have shot a few different grains of their 300 blackout and absolutely 0 issues. Pretty soon my safe will only have Gorilla Ammo in it.

    Jordan,

    I see that Mike has responded to you in e-mail. I apologize we missed your first request, things here are really crazy. The 205’s with their blunt nose can have feed issues, the only suggestion I have is try different mags. PMAG’s seem to present the projectile higher into the center of the chamber for better feeding. I have had people say that a standard mag not a Blackout mag sometimes feeds better as well.

    It’s all I use for defense and predators! Absolutely the best.
