What is the shank diameter of the Savage (Cabelas) #12 in 6.5 Creedmoor with 4.4" bolt spacing?

I'm thinking that the 6.5CM chamber will clean up 100% if reamed to the new 6.5 PRC

Lots of take off 6.5CM Varmint barrels around that are an inexpensive way to get into this new cartridge......Why..Because we can !
