Okay fellas, I have a sparrow that's rated for mag and 17 hmr. I threaded my 17 hmr and yeah it's not the quietest but I have no regrets on threading . I have a 10/22 mag and considering threading but curious what the reports going to be like. I hate to de value the ruger anyways, it's like new with dual extractors. I don't shoot it much but thought I might if it were suppressed, I love to shoot my 10/22 lr suppressed. Thanks again.
