In my never ending quest to find my next rifle, I started thinking. (Scary, I know.) I'm sure this has been done, but can't find much on it. Has anyone necked a 300 WM (not the wsm or rum) up to a 338. How would it compare to the 338WM? Would it be worth doing? Mainly used for deer and elk. Or would you be better off sticking with the 300?
