I just built this rifle and am concerned about the tang binding with the stock. Is is possible to use cardboard to space up the action such that the tang doesn't bind? Also, can you give me some insight on how to correct this in a more permanent fashion. I'm assuming bedding the action would be the permanent solution but wouldn't the rear pillar need to be raised to float the tang prior to bedding?
