When the bolt is closed the lugs should e vertical. Upon opening the bolt, the extraction cam should engage when the lugs clear the seats and the bolt should move rearward the full depth of the cam. If everthing is right, the rifle can be cocked by simply raising and lowering the bolkt handle. If not, the bolt will have to be moved back a little further than the cam will move it. There are some other aspects as well (cocking cam, cocking piece, trigger sear etc.) but this the main part.
Most, if not all, recent Model 700's have no primary extraction, will not re-cock without pulling the bolt back a bit, and the lugs are not vertical. In some special cases, everything which can possibly be wrong with a bolt, is. It is difficult to understand how or why this situation stands. There is no QC system in play. GD
