That's because most gun writers apparently followed Hornady's company line that the Creedmoor was a brand-new design. But when I first opened a box of ammo and took out a round, it looked very familiar, somehow. I measured the case and yep, it's the .250 Savage in slightly different form and caliber.
Actually, the easiest and cheapest way to make Creedmoor brass cheaply is with .22-250 cases--though the Hornady brass is VERY good and reasonably priced.
