I believe the all time reference on this subject is known as "Hatcher's Notebook" by Julian S.Hatcher.
Described by one of the sites selling it as:
"For shooters, gunsmiths, ballisticians, historians, hunters, collectors...the personal reference notes and experience of more than fifty years as a small arms engineer, trophy-winning shooter, technical gun editor"
