22 creedmoor factory rifle

Apparently it's possible to rechamber 22-250 to 22CM.

If you can find a 22-250 with a 1:8 twist that could be a good option. Tikka do some but only in varmint models.
 
I’ve seen on some other forums where a fellow out in California (Shaen Rifles?) has rechambered some Tikka 1:8 .22-250’s to .22 Creed. His customers seemed happy.
