Mike, I did not see that Mausers are on your list. Of course Prechtl, Ritterbusch, Johannsen, GMA/Breeding and Smithson are all Mauser-based guns.

So my answer is: MAUSER.

Weatherby = pimp gun.

Winchester Model 70 pre-64: Nice guns, but safety problems due to poor gas handling and weak metallurgy that makes them dangerous if overloaded

Winchester Model 70 Classic: so-so quality, and does not have the great feel of a well done Mauser.

CZ: A half-assed Mauser. Better than a Weatherby, and in general a reliable and safe gun. But it does not have the look and feel that I want.

Ruger: A quarter-assed Mauser. It would not cost Ruger much to offer a better safety and put an Obendorf bolt handle and 2 square bridges on its action. Plus a recoil lug on the bottom of the action and on the barrel instead of that queer plate assembly. Then they would be 80% of the way there. As it is, I have little interest in a Ruger. Also, have you noticed that almost no one builds a custom gun from a Ruger RSM?
