DALLDER,
I am a big fan of CCI Subsonic 40gr HP. I have used it in a bunch of different .22's, some match rifles, most hunting rifles. All of them shoot it very well.
My current favorite, and most accurate repeater I own, is a Ruger American Rimfire Compact with a fixed 8x Leupold scope. I have shot 5 shot groups with this rifle and the CCI ammo that are under 1" @ 100 yards, but most groups run just over 1". I have used these bullets on raccoons, possums, squirrels, and crows. They work really well.
Here is the link to really good prices for the ammo;
