I buy Loadbooks for each caliber I load. The Loadbooks have all the available data from the various bullet ands powder manufacturers. They are normally under $10, to boot.
Why buy an expensive hardcover data book, particularly when 95% of it's data is for cartridges you'll never load?...
To my great mortification, my father once told me; "you care nothing but for dogs, shooting, and rat catching, you will be a disgrace to yourself and all your family"
