The most pristine looking brass i have ever seen! This is the only ammo i will run through my CMMG Banshee from now on, Price is better than most, and shipping is also cheaper than most. Very happy customer.

It’s the only 300blk subsonic ammo I buy now. You can’t beat the price, and it’s 🤫

Great 300blk subsonic ammo! I’ve had trouble getting ammo to feed and eject reliably with a suppressor on an HK53 with an 8.2″ barrel in both semi and full-auto.
This ammo is the solution. In addition to being 100% reliable, it’s very accurate and seems to burn cleaner than other brands I have tried.
I’m so impressed with this ammo that I just ordered some of Callaway’s 300blk subsonic Boar Axe ammo to try out for night feral hog hunting.

Honestly the best subsonic 300 blackout I’ve shot (and I shoot a lot of 300 blackout) the brass is beautiful, it cycles flawlessly, seems to be a lot cleaner than most, and whatever their doing different makes it much quieter than the competition. Oh, and above all, it’s more cost effective than most any regular supersonic fmj you could fine. Kudos to these guys.
