Answers to some of your questions regarding what action/bolt spacing can be found here: http://www.savageshooters.com/conten...Action-Lengths
Its neither stagger or center feed, but if it's not a dual port, the two outer action screws are the same distance apart as the center feed action, if that's what you're wondering. If forced, you could leave out the center action screw. If it's a dual port, it is it's own entity and the bolt spacing matches nothing else.
