The Montana is made with castings as a cost savings measure. If that matters to you?
By Pine Tree Casting, a Ruger subsidiary that casts the Ruger 77's. I do not see that as an issue.
Early U.S. made Weatherby's were cast and I have been told that Sako's are cast although I have been unable to verify this. Regardless there is nothing wrong with a good casting.
