Another comparable "hot-load" .22lr are the Aguila Super Maximum 30-gr. HP which are also very reliable for cycling semi-action pistols.
Not in my Walther P22. They were 100% unreliable
. No exageration, not a single round fully functionrd tye slide. It would eject the spent case, but not pick up a new live round. The P22 as been very reliable with other types of ammo from RGB to CCI MiniMag. My guess is that the light bullet didn't provide enough recoil force to push the slide completely back far enough to pick up the new round.
