I like the Kimber the best of them all, but to be honest, I can't see that any of them are better than the Winchester M-70 Featherweight and 2 of them are not as good. The Winchester has a better safety and a better extractor.
It is the same weight as the Proof Research and the Christensen. From my experience with them,(as a gunsmith I have mounted a lot of scopes on them and shot a lot of them) the M70 is just as accurate, and it's better looking then any of these. In fact an M70 FW that has been used in the field for 10 years is still prettier than any of these are when they are brand new.

And to all this I need to point out that an M-70 FW costs about 45% of the price of the Proof Research,
33% as much as the Christensen,
1/4 of the MG Arms,
and about 45%of the Kimber.

Sorry folks but I'd take the Winchester even if they were all priced the same. In my opinion is it better in some ways and as good in every way.
