Duly noted.

Per my statement about Mk V marketing hype, there are a number of facts and physics that infer that conclusion....

Roy's storied catalyst for pushing cup & core bullets faster was wounding and losing a UT mulie. That logic was an obvious cart and horse paradox, as I've never seen a case head stamp kill anything.

Roy's 9 and 6 lug bolts tolerances have less than stellar engagement. Should you be so inclined, wet one up with a Sharpie to confirm. Some larger caliber WM MK V bolts have become 8 and less lug bolts for those that have moved well beyond their first box of ammo.

All those extra lugs and OEM mag constraints combine to limit COAL for modern, slippery projectiles.

Pushing projectiles with beach ball BC's faster pale when compared to moderate pressures/velocities launching javelins.

Proprietary WM brass metallurgy and increased pressure limits reloading case life, barrel life and increases costs. There are far better modern options than WM that provide lower ES/SD, longer case life/reduced cost and magazine capacity/leg room for svelte bullets, particularly SAUM, WSM and PRC/RCM. Personal preference is 308 parent necked down (7mm, 6.5mm or 6mm) and Creedmore for best bang for the buck.

Twist rates don't provide requisite rpm for higher BC's in some WM calibers. Same goes for the 1940's throat geometry. Your .308 is more than likely a 12-twist that really limits BC options.

26" barrels, wood and blued carbon steel are for those that don't hunt in wet climates or do much vertical in a season.

Weatherby triggers are at the lower end of the bell curve when compared to modern options.

Roy's offerings are manufactured under contract, Howa being a major provider.

New Mk V's are in the $3k range. Discerning minds will opt for finding a SS donor rifle and putting together a package that melds chambering, throat, mag constraints, twist, moderate recoil, weight and other preferences to a slippery bullet with excellent external and terminal ballistic characteristics for far le$$. Might even make it so fun that it is used more than a couple days a year. Anyone with a computer running JBM Ballistics can put WM marketing hype to rest. YMMV.

Horse back before the cart? *grin*
