This is what REMAN means
First as cited 300 rounds loose in nice little box. I'd give it 5 stars but 6 of the rounds were NATO 4 spike primer crimp reloads. There were a lot of Head stamps. 55% were 300 BLK from 21 manufacturers. 19% were 7 brands of 223 REMs, 17% were 7 brands of 556, 7% others including one 300 Whisper. So 44% of these round have remanufactured casing from another caliber. I reload and make these same things so it works for me. Just don't expect perfection, accept functionality. And I'll have to wait on that until I fire some to get the muzzle velocity. Sometimes folks will go light on the power to save cost on their end.
