Nope, it's 30Govt.03. He double checked and got back with me.
I'm thnking Winchester put both of them out there.
From what I've been able to dig up, there is a 'range' of serial numbers where these were produced in a 'batch'.
I would say he is wrong...no deadfuggin wrong!
By 1948 the 30-03 was long dead and gone. Even the first run Springfields were converted to 30-06 about 43 years before that.
Thanks for the benefit of the doubt. I am very aware of the history of the 30-03 and that's why I'm very curious and hesitant to believe myself, but this guy has never steered me wrong.
Not to mention a member here has sent me some information that may in fact conclude that it is possible some Model 70 actions had a 30-03 barrel put on them.
Thanks for being a dick, really warms my heart, not.
