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

300 Blackout 220 Gr TMJ Subsonic
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.

Best sbr/pistol ammo for 300 blk
I have a 10.5" aero upper in 300 blk and I'm hitting around 1065 fps on average I wish they loaded hunting or self defense rounds aswell

No issues
Ran 30 rds through a CMMG Dissent, no issues. Still waiting for my suppresser to get out of ATF jail so I can see how quiet the subs are.

Consistent ammo
Long time customer of minuteman. Ammo in all calibers has always been consistently accurate and reliable. Prices are competitive and customer service is dependable. The 220gr 300blk run flawless, group consistent, and sound great in a suppressed 9in rifle. Will be a lifetime customer.

.300BLK Ammo
I tried MINMAN 300BLK 220gr cartridges as they mentioned they would run 1050fps in an 8” barrel. My chrono test showed exactly that, but what was surprising was the fps variances was tiny. All my test shots came in between 1057 and 1063. I’m used to seeing easily 20 to 50 fps variance in the same box. Still more tests to run as I get time, but better consistency in velocity has to help my groups. Bravo MM. I like this stuff! B

Immpressive
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.
