OK so this brings another question to my mind Sharpshooter. If the Savage, and Remington too from what I hear, are marginal for this size cartridge, why is the Weatherby Mark V considered to be strong enough for cases this size? It's not a bigger action so I've never understood that. It has the same size receiver diameter IIRC, or very close. It also has the same size barrel shank and thread pitch as a Remington. And from what I've read about the measurements taken on the surface area of the 9 locking lugs, there's no more bearing surface area there than with a dual lug bolt. So what's the deal with it? Some sort of super duper heat treatment? That's about all I can think of. I read a lot of writings by, I believe it was Kirby Allen, who had done a lot of testing and his measurements were showing the Remington lugs to actually have more surface area than the Mark V's 9 lugs. Not trying to be argumentative, but am just genuinely curious and want to learn more.
