I played with my brother's 8" 300blk with Sandman-K.
Even with subsonics, it's not hearing safe. Granted, I was shooting it indoors so it might be a little better outdoors.
He carries it with supersonic ammo. It's his patrol rifle. he said might as well use a short 300blk instead of a short 5.56 since his department allows it and the -K knocks the edge off a little. He's only shot a few rounds outdoor without ear plugs during a training session so everyone can hear it.
