I've used the CB caps for years in my 22 designed to shoot S-L-LR cartridges with no problem. I like the CCI Quiet-22 for use in my LR only guns. Most of them will manually feed just fine. Only exception is the dang Sig Sauer Mosquito which doesn't like much anyway.
They are accurate and lethal at appropriate ranges. When I lived in town I used them in my backyard to control a dog size pest problem without alerting the neighborhood. Very effective.
