Actually you are wrong, I just read today an Article in Sniper's Paradise webpage that the Savage12BVSS Varmit Rifle (Short Action) uses a "cut-rifling" barrel. Read it!
I beieve they are the only company that usually uses the "Button Rifling" process where the grooves are literally pressed or ironed into the steel bore on the majority of their rifles.
I already can tell what kind of guy you are, Thanks!
