I just tried some .22 Hades in my cricket 2 this morning and they were shooting awesome. I set up the chrono and adjusted the cricket to shoot them at 920fps and they were shooting small holes at 50 yards. I know a lot of people say the FX Atomics are the same as the Hades but I've tried the Atomics and never got them to shoot as tight of groups as these hades...
Here's a pic of a full mag at 50 yards...14 shots....
