Yep!
It's amazing how various companies keep inventing "new" rounds, yet somehow the cases are often closely related to much older ones. The first time I saw a 6.5 Creedmoor case, it looked to me a LOT like the 6.5/.250 RCBS Improved, which differed mainly in having a 28 instead of 30-degree shoulder.
Yes Sir, you are correct.
