The big difference between the Creedmoor and .250 AI (aside from the bullet diameter, of course) is that the Creedmoor has a 30-degree shoulder angle, and the Ackley Improved use a 40-degree shoulder.
In reality the 6.5 Creedmoor is more like the .250 RCBS Improved, which used a 28-degree shoulder. Which is why I didn't refer to the Creedmoor as an AI in my article, but a "6.5/.250 Savage Improved."
I am sure rifle loonies everywhere are necking the 6.5 CM up and down in search of the perfect cartridge. Whether Hornady will do so is debatable.
