More kudos for Rem's sub-sonic. Does evything quite well in both my 10/22s - but, about $15/brick around here = not exactly "cheap" but not too shabby compared to premium "target" .22LR.
Too, I've had really good results with CCI CBcaps. They're really short so don't work in LR mags but fine for revolvers or any single feeding straight into the chamber.
