Oh, they'll cycle the action...the problem is that when you shoot anything but LR the bullets will get start getting stuck in the barrel once the barrel gets to a certain dirtyness point because half the power of the .22 cb long rounds is being used TO cycle the action. I've never been fond if having to push stuck lead out of a barrel...
It'll fire 'em...but it won't like it
