have shot a walther p22 in my backyard before, quiet enough, etc. 16" barrel on 10/22 suppressed......quickly figured out it ain't near quiet enough to pull this off.. Ok subsonic ammo, what else guys...this thing is not near what I was expecting...I know ammo is going supersonic, but how do you all get yours to shhhhhhhh? gemtech outback on 10/22. thanks. maybe just a little quieter than not suppressed and that is good as it gets?
