    My fav .300 blk subsonic

    Posted by Brutsey on 17th Apr 2023

    This is really high quality ammo, and with the sale made the price right for me to pick up a case. I have several boxes and have never had any FTF or FTE.

    Works great in the mini fix. Rifle doesn’t care much for hard primers and these work fantastic.

    300 Blackout 220 Gr TMJ Subsonic

    Posted by Charles Hoover on 16th Mar 2023

    Very impressed at how fast I got the product- shipped the same day, I received it the following afternoon. I have not had a chance to shoot any yet, but nice looking factory ammuntion, well packaged. I will definitely be ordering from minuteman ammunition again.
