I've heard it said, yes you CAN suppress / silence a 223.

But can you suppress it to a level that is hearing safe? As in: can supersonic 223 be suppressed to a level that will not cause noise induced hearing loss indoors for a short duration like... 5 rounds or so? How about on an open range?

Why do I ask? Because I thought it was impossible so that's why I figured an Octane 9 would be everything I need. Subsonic 147 grain 9mm's, and subsonic 300 blackout which would be super quiet for both.

But then I got to thinking..... If 300 blackout is only going subsonic, it's performance compared to 9mm isn't going to be that great is it? The subsonic projectiles aren't that much heavier than 9mm.. Might as well skip the 300 blackout and go with a AR9 or see if 223 can be hearing safe.
