Blue printing does not solve other problems that may exist, It just helps to eliminate some problems
that may later plague your accuracy.
I will not build a rifle(Any rifle) without checking them because they can be the difference in a 1/2 MOA rifle and a 1/4 MOA rifle. Note: I even check new actions and never fail to find something wrong. (Even custom actions and bolts).
To have a consistent degree of accuracy rifle to rifle everything must be true to the bore and square.
Sometimes parts that are not square or centered may cancel out the error and shoot well, But more
often than not these poor parts compound the error and prevent the rifle from doing its best.
Lapping a bolt is only good if both recoil lugs are in some kind of contact and can be lapped to 100%
contact. in your case I would recommend first truing the bolt on a Lathe and then lapping for a perfect fit.
Also if you have the action trued a precision ground recoil lug should be used.
Blue printing is only a part of the total accuracy package, but a very important part.
