By far "Rifle Accuracy Facts" by Harold Vaughn is the best single most extensive book backed by tests and scientific measuring equipment.
He provides the reader with some very indepth studies and answers them with tests. His book is one of the best if not the best read I have read on anything to do with the accruacy of a rifle.
Some quick examples; in one case he examines the symetry of the rem 700 action, he then matches the holes found on the receiver and drills them opposite of original position to study how this affected accuracy then he reports on hsi findings. Variable pitch threads and how they make contact and how it affected accuracy with some very neat photos and some very indepth sometimes uncomphrendable material.
Some areas of the book went way over my head while others were very on the spot for accruacy.
I would highly recommend that you purchase this book.

Through years of research, he examinded a variety of gunsmithing and handloading issues in search of the ultimate in rifle accuracy, including barrel-receiver joint motion, barrel vibration and rigidity, chamber and throat design, case neck tension, and bullet imbalance.

Sadly he passed away this Oct and will be missed by everyone who knew him. I cant think of any other member of the shooting sports who has contributed so much information as he did in his book. You can pick it up on amazon.com for around 25 bucks.
