    So glad I came upon minuteman munitions. Was having a hard time finding subsonic 300blk rounds. Shot them through my DDM4 PDW. I loved grouping.

  • Super nice ammo

    So you want your 300 blackout to turn into a pcc? Here's your answer. These little dudes are so gentle to shoot, it feels like a 9mm pcc. Accuracy and grouping was so easy, standing, I had a range officer really impressed with holes in holes and holes touching in a 5 shot string. Wish it was cheaper but I'll buy more when the suppressor arrives.

    Package came very quick and in quality packing. Haven’t shot them yet so I gave it a 4. I am sure it will be a 5 for sure. I also called to inquire about shipping notification. They answered right away and were very helpful. I will absolutely be ordering from these guys again.

    Just purchased a 300 Blackout pistol. About to start the process to get a suppressor and wanted to see if the subs would run with out it. They did! Well made ammo at a reasonable price for the times.

    This is a local company that produces a great product. MOA thru my DDMV4 at 50 yds was .6” Great burn, no misfires thru 300 rounds. Would definitely recommend. Just need more!!!

    This ammo is fantastic. I have a 10.5" pistol with a SilencerCo Omega 9K that I use for coyote hunting and competition. This ammo is the quietest load that I've found for it. The tone is superb. The grouping is terrific.
    The quality is top tier. As long as Minuteman keeps making this ammo I will keep being a customer. Great job!

    Great ammo, great customer service and overall great company. I got an email when the rounds were available, I ordered, they shipped quickly, I got the box it was damaged and they emailed me back in 10 mins on a Sunday. They made sure my order was right. You don't find service like this these days especially with gun/ammo places. Keep up the good work you will have my business. Thank you.

  • Fantastic, Consistent, and Available

    First time purchasing 220GR from Minuteman Munitions. I could not be more pleased. Put 300 rounds through my SBR SR-30 and I am very impressed with the performance and consistency. After shooting many brands of sub ammo I can't stress enough how important it is to ensure that you have ammo designed to perform in a SBR, which this ammunition is. The icing on the cake is the fast order processing and shipping time. I placed my order 2 days before a range meetup and I had the ammo in hand, in time. Great company, great product, and I will definitely be ordering my subs from Minuteman Munitions in the future.

  • Great Ammo, Amazing Service

    Just had a great experience with this ammo. Put 300 rounds through my SR-30 yesterday and cannot capture the words to describe how pleased I am with this purchase. Even better that I had the order in hand 2 days after placing my order on the website. 5 star ammo and 5 star service is tough to find these days, but Minuteman Munitions nailed it. Thank you so much, please keep pressing so I can buy more!

    Can't complain, this stuff works in my Sugar Weasel PDW without a problem. Zero problems, usually always some in stock, insanely fast shipping, and great folk.

    300 Blackout is hard to come by at a reasonable price. I placed my order on Sunday evening and received it Tuesday! I got good feedback about my order as well. I'm in NC and expected fast shipping but would not have been surprised if there was a day or two delay in our current times. I've only fired a few rounds to see how they cycled and they all went bang and flew straight. I'm happy so far and plan to buy more. Thanks Minuteman!

    For training rounds, I won't buy anything else. They are extremely consistent, phenomenally priced and the shipping is fast. 10/10 would recommend.
