Excellent for suppressors - CCI Ammunition Quiet-22 Semi-Auto .22LR 45 Grain Soft Point Rimfire Ammunition

This is the quietest round I have found to use in suppressed semi-auto pistols and rifles. Functions reliably in almost all of my semi-autos, with the exception of my S&W Model 41 which doesn't do that well with it. I'm skeptical if the other reviewer who said it doesn't work was actually using the Quiet-22 Semi-auto or was using the much more common standard CCI Quiet-22 round. One is a 45 grain bullet at 835 fps (Quiet-22 Semi Auto) that will cycle almost all semi-autos reliably while the other is a 40 grain bullet at 710 fps (Quiet-22) that will not cycle in semi autos.
