www.hodgdon.com I use it frequently and has always been pretty much right on. They list Hodgdon, IMR, and Winchester powders. Even have a printable version.
Ammoguide is a pay site but has data from almost all the manuals plus user submitted data and a great list of chamberings.
It's a bit clunky but to me it was worth the price.
I don't think that there is any relation between Accurate Reloading and Accurate Powders
I agree. I'm new to reloading and check all the "other" sites in case I might miss something. It's not the sites per se... but I've realized that there is as much if not more knowledge being spewed on this site than anywhere else. The "Hide" guys know their stuff!
