They don't offer it in any of the fast .25 bores or I would probably have one.
Ruger has released the American in 25-06 - it was the dealer incentive special a few years back. If the dealer sold to a certain level - Ruger sent them the 25-06 as a special release.
I have .260 version from 2-3 years ago.
25-06 in the Predator format of green stock and threaded muzzle, they are on the auction sites every once in a while.
