After .22 Shorts, there was a "CB cap" which had less powder than a .22 Short, and then there was a "BB cap", that had a bullet that was propelled only by the priming compound. With .22 Shorts being as uncommon as they are now (when I was a kid, we shot mostly shorts because they were significantly cheaper than .22 Long Rifle), CB and BB caps may be very hard to find.
