Pellet and Shot Cycle

I know some barrels prefer certain pellets, but can the shot cycle also determine what pellet your gun likes. As an example, my hw95 loved 7.9 cpl's, then I put a vortex kit in it and cpl's do not shoot well out of my hw95 anymore. My RWS 38 also changed what pellet it liked after I tuned it. It went from really liking RWS super domes to not caring for them at all.
