Pat,
I have read the book (borrowed) and found it to be interesting.
You will find a wealth of information in these forums which will probably be as valuable though. I don't want to knock the book, but there are a few areas where I take issue.
One is his method of "proofing" his guns. His apparatus for holding the gun actually helps to keep the gun closed which is not an adequate approximation to real life. Also, he goes on about soldering barrels into a monoblock being inadequate, yet he has no problem dove tailing and soldering lumps into the monoblock. This seems to me to be a much weaker joint than soldered barrels based simply on the surface area differences.
Maybe somebody on the forum can educate both of us on this.
