All mine are very loose in their own drawer. All my pre 64 Mod 70's shoot very well without them being present. I tighten the front action screw very hard, just snug up the back screw and only tighten the middle screw until the floor plate will close. My theory is not to introduce uneven stress to the action. I always do this except for actions which I have stress free glass bedded as the benchrest shoots do.
