I was able to get 2 boxes of CCI Quiets -- Range day yesterday Ran a box thru my Suppressed Ruger Precision Rimfire -- was using my rimfire spinners at 26 yards (about a yard behind the 25 yard target line). The rounds would consistently drop about 2 inches, from my usual point of aim; couple rounds later was dialed in. Almost no noise -- I hear a constant ringing anyway, but I heard a small click when I press the trigger and a clang when the bullet hit the spinner. Finally found a use for the CCI Quiets !!!!!!!!
