Have been a fan of the CCI CB Shorts for quite a few years now. They are squirrel head accurate to about thirty yards from a Remington 550-1. Quieter than most pellet rifles, the Remington's floating chamber cycles them just fine. When my neighbor asked what kind of ammo I was using I told him: "Special stuff, loaded with 'Hush-a-boom.'"

Recently tried some of the CCI Quiet 22's and they are excellent. From a 34-1 they are no louder than a standard .22 is from a rifle.
