RE: 300 Weatherby Magnum
No matter which one of the 30 cal. magnums you pick, at any distance you "should be shooting at", what ever gets hit won't know one from the other!!!
One thing that is "absolutely" for sure, use the BEST bullets you can at these velocities!!! For me, 180 Nosler partitions have been a pretty good choise in the 30 magnums for elk sized animials.
