True, but the Ramshot data does list that specific bullet and powder combo, and I worked up loads using both the Win cases and WSR primers they list, as well as my preferred LC cases and other primers. Other than chamber variations, that data was as specific for my load as you'll ever find. I'm not new to this; you can argue all you want about that load being too hot, but you're doing a lot more guessing than I did.
If you haven't used the Western Powders guide for their powders, I recommend it. It's more comprehensive data for a wide variety of bullets than most manuals, and is a better reference for their powders than any other data source I know of. It's a free download anyway.
