I like to bed most things tight. This includes the Ruger m77 and Winchester model 70 and CZ550 and old M1917 sporters I've glassed in the past.. However, when bedding, I don't snug the action screws down tight. Just enough to keep the action in the right spot. This also keeps you from torqueing/twisting the action. The action should lay in there in a neutral state while glass bedding is curing. You can later torque the action screws down tight or to spec after the bedding compound has cured.
