.300 Blackout 200GR FMJ - SUBSONIC - REMAN - 100 Rounds
All cases looked in good shape. Ran all through a shell checker after I saw that the cases were cut down reformed 223/5.56 brass. Shot 40 rounds through my 16" CMMG with AAC suppressor. Half were not subsonic. A few sounded like they had trouble pushing the bullet out but did eject the brass. All did ring steel at 100 yards. Tried 40 of my own reloads and all worked great. I'll stick with my reloads (as soon as I can find more powder). Thanks
