Mine is in the Mark X, Whitworth model made in Manchester, England and is accurate!
And yes it is a versatile rifle if loaded right. Here in Colorado it can do quite well on elk,and moose.
When I first purchased the rifle it was going to mainly be for bears in Alaska or a safari in Africa. None of those hunts every came to be, seem like my job was always on high priority when I started to make arrangements for one of these trips.
Anyway I can still use it just to have the option of loading it for various types of game.
