I have two 25-06's (soon to be three). One is one I built on a Mauser action the other is a Ruger #1. The Mauser will still drive tacks at 100 yds but it has a 1:10 twist and doesn't like the new longer bullets. The Ruger is a 1976 Bicentennial with a custom stock (Ruger built) and has become a 'collectors' item so its been retired. Hence the new build.I think Weatherby is the only manufacturer who chambers for it.
