I tried "quiets" in my 22/45 and 10-22 with a Sparrow. Would not cycle in a semi. They are great in a lever or bolt. They advertise no hearing protection needed.
Nice! I bought mine used when I was 14. Love it! I put an old steel tubed Weaver 4x on it and killed tons of squirrles, rabbits and groundhogs with it. It is by far my favorite .22 out of at least a dozen in the safe. It goes great with my Model 88.
