Mugsie, Good advice above :) Just as important, chk that action isn't in a bind (stress free bedded) Lay the rifle on its side so barrel weight doesn't come into play. Alternately screw & unscrew action screws. If action lifts off bedding when unscrewing, the action is in a bind and probably won't give you best accuracy. Minor lift of a few thousands probably won't cause problems. Another sign is with bbl supported in vice the action screws should come to an immediate & sudden stop when bottomed out. No amount of hand torque should allow screws to turn more than 1/8 turn (definitely no more than 1/4 turn) past sudden stop. In other words, the action screws should NOT tighten gradually. I always strive to achieve the above results so I KNOW its done right. And, yes I've had to redo a few. ;D
