My vote would be for CCI HV or SV as being just about the cleanest overall for commonly available 22LR ammo.
The problem I'm having with the Taurus Tracker after firing 60 or so rounds is a few cartridges start to back out of the cylinder chambers after one or two are fired, causing the action to bind. When the cylinder chambers are clean, this doesn't happen, only when they begin fouling.
