Also beware of gun magazines. Over the years I have seen numerous overloads published as safe. Don't think that because a magazine specializes in hand loading that they won't steer you wrong either. Bigmaxx is right, put your trust in bona-fide loading manuals, and double check them against each other.

That’s not to say that loading information in gun magazines has no place. When I read about a cartridge I’m not familiar with, I like to see what various components are capable of, and what works well. But I won’t load and fire those combinations based on that magazine article.

There is one online source I know of that I feel is safe to use. That is the Hodgdon website (http://www.hodgdon.com/).
