They are mixing 2 different powders into the case. I doubt this kind of powder data will ever be available to the public. Just imagine if Joe reloader got the charges for each powder backwards
And I doubt they can exceed what the reloader can produce anyway. Another thing, just cause it's faster don't mean it's better. I'll take a slower, more accurate cartridge anyday.
Just as a side note, I love Hornady bullets for reloading. But I've never shot a really accurate Hornady factory round. I'm sure many have, but I haven't.
