I had a Mossberg 500 and considered a Hushpower barrel but since it was FAC it would have been a pain.
True but I can shoot the subsonic loads without ear defenders, and having a friend fire it 100m away from me (not at me ) it was still quite loud with supersonic cartridges.
I've had noise complaints before, land isn't suitable for a .22RF and the .410 I had was lacking on crows.
