Actually, the more I think about it the more a 22 Creedmoor makes sense.
I know a few of the 'makers' have been skeered to do anything but a 1-14" twist for the 22/250 because of Saami, it's always been that way, etc etc.
If the come out with the 22 Creedmoor and start it off with a 1-8" twist to begin with, all is golden.
This!
Plus 22-250 AI performance without the fire form
