Blue Printing?
 

I understand the advantages of lug lapping and truing the action, but what exactly is blue printing an action and what are its advantages? Thanks for any info.

"Blueprinting" refers to bringing all surfaces and dimensions of an action into exact alignment and specification. The advantages are the elimination of any factors such as torque, or misalignment that degrade accuracy.
