I don't know about the other jams but that one in atr's link looks suspiciously like at least one badly cut chamber. Rimfire brass should not be able to bulge like the owner found. The bulge is causing the casing to lock back with pressure against the recoil shield instead of moving back into the cylinder after discharging. It's the pressure against the recoil shield that is causing the lockup.
The gun and examples of that brass needs to be sent in for warranty replacement of the cylinder.
Sadly this does occur more with S&W products nowadays than on the past. They don't seem to take as much time with quality control inspections as they used to do. In the US S&W is prompt to make this stuff right. But up here in Canada the outfit which is the warranty center is over worked or under staffed and returns take way too long.
