Here's a pic of the stock after 40 shots.

you need to torque your action screws to 65 inch pounds not 40....loosen your screws then torque the front to 10 inch pounds then bump the butt of your rifle on the floor...give it a nice firm bump but dont let it bonce and dont lift the butt off the floor...now torque the rear screw to 10"lbs then torque the the front screw to 20"lbs then the back screw to 20"lbs...now torque the front first then the rear screw up 5 inch pounds at a time until your at 65 inch pounds....remember FRONT SCREW FIRST.
the reason you torque in this order is to pull the action into the alum stock evenly.
