I think Aguila sells both '.22 short' and CB ammo. I don't have Aguila, but I do have Remington ammo, some "CBee low velocity .22 short, and some "high velocity" .22 short. I can tell you that the CBee short functions fine in a Winchester Model 61 pump, has a nearly nonexistent report, and will take out a red squirrel in the bird feeder at 15 feet.I would be careful with that brand of .22. There is no powder in the shell, just the primer and the bullet. My LGS says not even though they sell them. The primer may not be sufficient to push the bullet out of the barrel. I won't go near them. A real .22 short is way better. It has powder.
