It'll be nearly as quiet as a dedicated .22 caliber suppressor but it'll give you a lot more flexibility to use on other guns up to 6.5/.264 and some even have enough clearance to work on .270 stuff. If a dedicated .22cal suppressor is what you want, no problem there are plenty to choose from but I know if I was doing it all over again, I'd have gone straight to a 6.5 can and skipped the dedicated .22cal centerfire suppressor.
I'm a big fan of TBAC suppressors so one of their Ultra 7's in whatever caliber you choose, would be my first choice with a SAS suppressor as a close second. They are both top performers, with regard to Db reduction, accuracy, and lightweight, in the suppressor world. Others make a great suppressor as well but those two would be my top picks.
Also, for your own peace of mind, becasue it can sometimes be maddening when you're trying to pick that "perfect one", if you do much research you'll find there are actually quite a few very good suppressors on the market and a lot of our recommendations are based on personal favorites.
