Vaughn does most of the work in the book with a Remington 721 in .270 Winchester with 90 and 120 grain jacketed bullets. Why, you would ask, would that be relevant to a cast bullet shooter? The answer is that it is not that gets his .270 to shoot ¼ MOA groups at 200 yards with hunting bullets, but how he does it.
Looking at the pictures, it appears that he worked on this process for over 20 years. And he shares what works and doesn’t make us read about all the things that didn’t work. When he gets to the end with the .270, he starts with the 6 mm PPC and then a rail gun in 6 mm BR. Everything is backed up with instrumented data, that he tells you how to build, programs to run on your computer and more than I cannot really use. But he destroys many myths: molybdenum disulfide does nothing but cool powder gases and reduces pressure, weighting jacketed bullets closer than 1% is a waste of time compared to working on seating depth and (my favorite) the Remington 700 barrel mounting system is the worst possible way to put a barrel on an action. Scope mounting, bedding and tinkering are all covered in the book.
The book is a cult favorite of barrel makers, custom action makers and do it yourself gunsmiths. Every process is detailed about to making a rifle shoot. So even though it doesn’t even mention cast bullets, the principles are the same. My engineer friends tell me the appendixes are worth the cost of the book on how to build and set up the instrumentation to gather data.
The only flaw with the book is that it is out of print. Used paperback copies sell for about $300 and mint condition hard backs in the $700+ range. You will have to post bond, your oldest son, to borrow a copy.
