Yeah CCI is definitely quality. CCI MiniMags are my overall favorite .22 LR. Speaking of subsonics, I got a few boxes of Aguila CB -- these have no gunpowder, the bullet is propelled by the primer only. Now those are quiet. They fire a tiny 20 grain bullet, but it still packs enough punch to penetrate cans and such. About as powerful as a good pellet gun I guess.
