Clever and clever lite are 1oz loads that cycle erratically in semis due to the lowish velocity and shot charge not giving enough recoil energy to cycle the action. They do work quite well in gas operated guns and run in inertia guns though.
Those std 1 1/5th loads obviously give more of a thump.
The club i belong too used to buy clever but has gone to target products because of availability. Their olympic and v1 seem to cycle semis fine.
Yours will improve with wear im sure.
