I have a Win SX2 with the light load gas piston in it. When it is fully loaded and with the sidesaddle full, it will "short stroke" if I am using regular target loads. It runs like a top as long as I use hotter loads such as Rem Nitro 27s. It will also have this same problem if the gun is not held against the shoulder. Has anyone tried shortening the main recoil spring to make it easier to cycle with lighter loads ? Thanks
