How close would these two be?

Read an article on the '6mm Creedmoor' which made me wonder if that round was being commercialized.

I recall JB mentioning the 6.5 parent round can be made from 22/250 brass, so figured the 250AI would be perhaps identical ballistically and perhaps almost the same in specs as a 25/6.5 Creedmoor.

Anyone?

I think there would be some following of 6mm, 22, and 25 versions of the Creedmoor and based on past success of calibers in this country, would expect the first two might be more popular. A 22 version would be similar to a 22/250 AI, as a 6mm close to a say XC. A 25 Creed would eliminate brass forming for a 250 AI if mfg.

IF they ever are produced, I hope to see a fast twist 8" bbl used in the 22 and 6mm for heavies and of course a std. 10" ROT in the quarter bore.

I just wonder how 'niched' the Creed may be to competition shooters and if a larger opportunity exist with other small bore sizes - 22 thru 25. No doubt a 5mm version would be smoking hot!
