Normally I am a big believer in having an actual paper manual for technical things (yay Haynes manuals!), and I have purchased some of those Lyman 15-page softback manuals, but given the proliferation of powders not in the books I have seen, I am wondering about spending $40 on a book that may be obsolete. It seems pretty easy to track down starting loads online for free. If there really is an authoritative book I am willing to spend the money, but just poking through a few in Sportsmans Warehouse, I couldn't see the advantage (I am reloading very common cartridges like .30-30, .45 LC, etc., not some rarer wildcats like .257 Roberts) . Am I missing something?
