you are EXTREMELY ignorant, dude. The best .22lr cans reduce the sound by 40db's. One time, demoing my silenced Ruger .22lr pistol for a friend, I held the bolt shut with the palm of my non-firing hand and fired it from our bedroom, down into a sandbag in our closet, in my gf's house. She was doing the dishes, around the corner in an alcove. If she'd known, there'd have been HELL to pay, but I knew that she'd never hear it over the noise of the dishes, her scrubbing, etc.
I once saw 4 shots fired, full power 223 ammo,thru a "homemade" 223 silencer and AR15 auto, letting the bolt cycle normally, at a flock of turkeys that were 50 yds away, 4 clean kills with the softpoint ammo, and while the other birds fluttered a bit, ran a few yds, etc, they were still there.

anyone who "sees no use' for silencers aint been around much. they are very advantageous for home defense, having no flash at night and not blowing out your ears. they are very handy for disposal of problem animals, and for practice, too. Your animal control truck has one, did you know that? they shoot dogs at night, and they shoot deer on airport runways.
There's no reason to have a NOISY gun, actually. We've just been brainwashed into accepting the noise as 'part of the deal". Realistically, having a noisy gun makes no more sense than not having a muffler on your car.
