I grew up with weatherby rifles, my dad loves them. I hunted with them for years and years without ever knowing anything about accuracy, groups etc, etc.
I don't remember any of them giving us any trouble.
Right now I just have a few mkv sporters, one in 300wby and one in 340wby, both are very accurate. If I were to buy another I'd get that ultra lightweight in 300wby with tha 28" barrel just because it's cool.
"Cool" is the new 6.5-.300. If i was getting a new 9 lug that would be IT!
