    I ordered this a while ago and it’s fed through my suppressed PWS with zero issues. So far so good

    I have run 1000+ rounds through 3 different unsuppressed AR’s, both pistol, and carbine without a single misfire. They feed and cycle perfectly. Accuracy is very good also.

    Zero failures after about 250 rounds through a suppressed SBR.

    Tried these today and had zero issues. Getting ready to make a bulk buy.

    Dishonest company. Don’t order this and expect to receive it anytime in the near future. They did refund my credit card but lied twice in the email about why they never shipped it.

    I placed an order almost a full month ago. After 2 weeks I emailed and they said they were behind, but would ship soon. The end of the following week came, still no communication, and I emailed asking to cancel my order since we missed the video shoot for some videos on a Q Honey Badger to test the titanium suppressor. I still have not received a response, or any ammo, or a refund to this day, May 3rd. ORDER AT YOUR OWN RISK!! Very poor communication. Wish I could have left zero stars for this transaction which will be my last. Ridiculous!!

    Subsonic 300 blackout works great through my 16″ PWS. Very quite as expected. A bit on the smelly side, but for the price can’t be beat. For those complaining about lead times, sure, this ammo takes a while to ship, however that is clearly stated when ordering. Not sure how that is a problem.

    I’m used to the 30 cal variants taking a little longer to process and ship out and I expected these to take especially long after reading they are reloads. I’ve had to wait up to 6 months for 6.8mm ammo from Silver State Armory during the Obama days and I thought Octane Munitions was very prompt with their replies and provided satisfactory responses. Overall it took a few more weeks than what the site said but I understand supply and demand when you’re operating a small business. I will definitely be purchasing in the future when they are back in stock.

    My only request from this company is to provide an option to order bulk shipments for a later date; like 6-12 months in advance would be ideal.

    Order took long, but when emailed I got a fast response. Ammo is great. Accuracy is great and whisper quiet through my suppressor. I wish they had an option to notify me when the ammo comes back in stock or is available to order again. I will need another shipment soon!

    This ammo shoots well from my 10.5 “ barrel. I’m hitting same hole at 50yds. Shipping took awhile but this is awesome ammo at a great price. Going to buy more soon. Waiting to see how it does in my suppressor when I get it.

    I have run through almost 1000 rounds thus far and had no issue, it rund swimmingly through my AR and is quiet enough that I decided to invest in a silent capture buffer spring.

    Most inexpensive 300 AAC on the internet last time I checked, and the quality blew me away. Very consistent and easy to zero at 50 yards, and with an ACSS reticle red dot from Primary Arms/Holosun I had good results out to 100 with a minor holdover. Great looking brass and performance exceeded my expectations; I will try out the 150gr next.

    I’ve bought 2000 rnds and have run over 800 rnds through my pistol with no issues. Shipping does take awhile but if they can keep the price down “price has gone up” then the wait is worth it. Just do what I do and reorder before you run out.

  18. Rated 2 out of 5

    For the most part the ammo was good. I did have an issue with the CBC reloaded ammo on my 300 blackout which kept jamming. It was about 15% of the ammo I received from Octane so unfortunately I had to throw them away.
