For example-
It took me 6 months of trial and advice on how to get a Ruger Mark 1 to cycle correctly using subsonic .22 cal 60gr rounds. Reduced power spring, tons of polishing on the bolt, etc.
Still hear the boom of the powder charge though.... I can’t wait to easily go out and buy, or just build my own “can”.
If I were getting a sup[resser I would mate it with a feather arms .22 and then the 9 mil. semi auto.
