Has anyone ever necked up a 338 Win. Mag. to 375 and of course, built a rifle for it? If so, please give me some info on it. I know there are a number of 375's out there, but I have always wondered why no one particularly Winchester thought of making one on a 338 WM case?

has been done many times search under 375 taylor not realy a taylor but real simular to 416 taylor so they call it that. its ok the 375 ruger is the same thing with a little more case capacity.
