    Shoot some subsonic or supersonic ozark ordnance ammo for the 300 blackout and you’ll buy it there from now on! BEWARE: of other manufacturers that don’t specialize in the round. FTF 3% failure rate with most everything I’ve ever shot. Not with Ozark Ordnance, their 300 Blackout is down to a science and with expertise.
