I've been time stamping the snubbie episode, and there is a bit in there about .22 ammo selection.
Chris recommends CCI stingers or Velocitors. I can't attest to their effectiveness through a short barrel, but I can say that CCI makes the most reliable rimfire ammo I have found so far. In the 1,500 or so rounds of CCI I have fired through my 10/22, I haven't had a dead primer, and only a handful of misfeeds, all attributable to a dirty gun.
