i have a savage target action and the screw for the accutrigger adjustment fell out and is lost, will savage sell just the screw? secondly, i had a shilen barrel installed on the action and the head-space is tight, the bolt will close kind of hard on the go gauge but it will close and of course it wont close on the no go gauge. my question is will a tight head-space hurt anything? the bolt closes easy on fire formed brass that has been neck sized and i have no problem with new fl sized brass. i would hate to mess with it because the rifle is scary accurate now but if the head-space being tight is a safety issue i will reset it. thanks in advance
