I like CCI's "CB Short" 22 subsonic ammo for plinking. It's so quiet that when I use the stuff to euthanize the coons raiding the birdfeeders (head shots do the trick EVERY time) the cat sitting next to me doesn't even look up at the gun when I fire it. Ordinarily shes tearing to the other end of the house in mortal panic when I use regular short, long or long rifle cartridges. When I discovered this ammo I sold my Beeman Fienwerkbau Air rifle, cause I just didn't need it any more.
