So I'm building a long action with my son for a graduation present and we've run into a snag. I've got a stagger feed action and the bolt is dragging on the mag box. I know that's what it is because when I remove the follower and attached mag box the bolt cycles freely. I tried bending the feed lips down and I can't go any further without closing it off so much that rounds won't go in it. Could I have a center feed stock and that's the problem? The action dropped right into the stock so I figured it was the correct one. I also noticed that my short action center feed has a "side support" on either side of the magazine, this stock doesn't. I'm at a loss and he's expecting to go shoot it when he gets out of school today and I don't want him to be disappointed.
