I have a new from the factory Rem 700 action. 3 of the 4 holes for mounting the base are threaded perfect and the screw goes right in. The fourth hole has not cut correctly and the bolt to hold the mount on in that hole will not will not thread at all. I can't even get it started. Is there a way to correct this problem? Can it be rethreaded to accomodate the base mounting bolt?
