This is a book no longer in print (and usually priced accordingly if you find a copy), but George Frost's "Making Ammunition" provides an enormous amount of data and information about primer manufacture in Chapter VI. Frost spent his entire life in the ammunition industry (mainly at Western and CCI), and it is doubtful if anyone knew more than he.

The book was originally published by the NRA in 1990, and I have often wondered why it has not been re-printed as it contains so much useful information about all things ammunition-related.
