All too often I've witnessed new reloaders taking short cuts, skipping through the pages, this doesn't usually work out too well. SMOA

This reminds me of a guy I used to work with. When reloading Mr. Knowitall would flip open the book mumble, "I have this powder", then run his finger over to the max load.

Since no one has mentioned it, there are little handbooks with a compilation of data for one particular cartridge. It has excerpts from most of the popular reloading manuals. Only trouble is they tend to lag behind the most current edition of manuals. For about $10 bucks they are still a decent buy.

If starting out I'd consider a manual from a bullet manufacturer (Hornady or Sierra) and another from an equipment maker (Lyman or Lee). He needs to read the why and what for section before diving in. There are several dependable online sources for reloading data. Two I often use are Nosler's and Hodgdon.
For cast bullets Lyman is the gold standard.

Best wishes as you both give your knowledge and experience to the young man!
