		rascul 7 months ago \| parent \| context \| favorite \| on: The reality of firearm suppressors vs. Hollywood I've fired a .22 semi auto rifle with a sound suppressor and subsonic ammo in the past. It was maybe just a little bit louder than the Welrod in the video in the article. The noisiest part was the bolt cycling. I'm not sure how practical it was for anything more than paper targets or beer cans at near to mid range.

Many 9mm self-defense rounds are subsonic (e.g., 147-grain), so the practicality depends on the bullet design for the application.
