You didn't say, but I'm guessing you're considering the 7mm Weatherby Mag.
Recommend, instead, you get a rifle chambered for the far more common 7mm Remington Magnum cartridge. Ammo is more readily available, and cheaper.
Also, you won't lose much in velocity vs. the proprietary magnum cartridge (100fps+/-).
And, an added benefit, you can get the 7mm Rem.Mag. in any number of good rifles by
Remington, Ruger, Sako, Savage, Winchester, etc., and Weatherby too.
