On the Remington ADL the front screw should be very tight, the rear screw should be just very snug and the center screw(holds the front of the triggerguard, just barely above finger tight. The middle screw can really play hob with accuracy if overtightened, the other 2 are less sensitive. Make the front tighter than the rear and the center, just barely. I have even gone to the trouble to eliminate the center screws being screwed into the action altogether.. eliminates one more problem..
