So, what's the deal with Raymer's book? Does it have an excessive
margin of safty, or was I doing something wrong?

After playing with the spreadsheet for about 15 minutes, it looks as
though the weight calcs are VERY sensitive to a few parameters that
aren't well explained in the spreadsheet. Unless you know exactly what
those parameters are, I don't think you should trust the weight #'s that
you get. Maybe the book has in-depth explanations of what the
parameters are and how to set them.
