Could be the screws are too long. But, I just had the same problem with a Boyd's stock with my bolt being stiff. If I loosened the screw a little it was fine. I shortened the front screw a little and that didn't help. I went to bed it this past weekend and found out that I had about 3/8" clearance between the action and where it should be touching the stock. It was only touching on the bottom of the recoil lug and the tang. Put the action in a different stock and all was good. It was binding the action when I tightened the screws. That Boyd's stock is going in the garbage. I have another Boyd's for a short action and it is inletted fine. I must have just gotten a bad one.
