When you tighten down the action each screw should go from loose to tight in about 1/2 turn or less. Check it by torqueing the front screw then tightening the rear screw. Now loosen everything up and torque the rear screw and tighten the front screw. In each case when tightening the second screw it should go from loose to tight in 1/2 turn and come up solid. If it doesn't, you have a bedding problem.
