    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.

    300 Blackout 220gr subsonic

    Posted by Matthew on 13th Aug 2020

    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!
