I've read that Springfield went to a flat head butt plate screw from a rounded head screw specifically to have the screw head flush with the plate - for the same reason they went to an angled toe.  One of the things I noticed when I first got this rifle was that the large butt plate screw was not sitting flush with the butt plate. I hoped the screw just wasn't seated properly, maybe the screw is wrong, or the screw hole has something 'blocking' it.  The screw was seated tightly and is identical to the one in my Krag sporter (and there was nothing blocking the screw hole).  What I noticed when pulling the sporter screw to compare it was that the butt plate in that rifle has a counter bore (??) the thickness of the screw head on top of the counter sink.  That allows the head to be turned in flush with the plate.  There is no such counterbore in the butt plate screw hole on this rifle, resulting in the screw head sitting proud of the plate.  I suspect the butt plate is the problem but will defer to the experts.
