Never seen a bolt action drawing that amounted to more than napkin notes of just a few of the most basic dimensions.
For all that they are 'popular', nobody seems to be building them from scratch.
Even the few actions out there that have drawings, are reverse engineered, with a lot of by guess and by golly estimates as to dimensions and angles.
Edit: There is an entire book out there on the manufacture of the '03 Springfield, that goes into gory detail, but cannot tell you if it has dimensions and tolerances.
